The thing is no one likes to be told what to do...this is a gimme. So instead of telling each other what we should or shouldn't do (cas no one needs a second mother or father
) and everyone get's their knickers in a knot...let's look at what exactly is going to transpire here and what is trying to be pointed out....
Let's all just sit back, calm down, and think about things for a second.
(we will use this for example sake)
Let's say you wanted to breed dogs.
You wouldn't go to the pound and pick out a couple of "really pretty" dogs to "practice" breeding with, now would you (no, of course not)...even if you have people lined up to take them. That's just not how it works.
You are supposed to breed to better whatever specie you are involved with...not breed more "mutts" into that species community.
Breeding Veils, who have no traceable pedigree is kinda silly...isn't it? There is nothing for you to better. No tail type, no color pattern, no nothing. These are live animals..not a piece of paper that you can just wad up and throw away when you are done "practicing".
Do you have 200+ friends/relatives that want betta's? (I know you are thinking "yeah right, that won't happen to me. Like I'll even get close to that many."...well you can't have that mentality..you have to plan for WHAT IF) Because what are you going to do with 200+ baby betta's? What happens if 90% are males..where are you going to put 190+ jars? Can you afford to feed them live foods, afford to buy them frozen foods, buy heating pads and/or heaters to keep them all warm, buy water conditioner for them, change water daily, buy containers large enough to house them properly..do you have time to properly cultivate your live foods..so they don't run out? Not to mention what your water bill will be from using so much water every single day. That is alot of water. A single Beanie Baby box holds 56oz of water...think about that...56oz x 190 boxes x 90 days (at the least).
128 oz = 1 gallon.
56oz = 1 Beanie Baby box
56oz x 190 boxes = 10,640 oz a day
10,640 oz x 90 days = 957,600 oz for 3 months
957,600oz = 7,482 gallons of water..for a 3 month period. 
Do you live alone? Or with parents/roomates..what are they gonna think about that? What are they gonna think about all those containers cluttered about, sitting everywhere?
You can't give them away until they are 2 months old atleast...so what will you do with them until then? What will you do with them afterwards if people back out on taking them..and trust me...people always back out...that's how it goes with animals...things "come up".
The school idea is great...but what if there are no schools doing anything like that in her area? What then
? I know we don't have anything at the schools around here...they sell candy..not peddle fish. They have a contract with the company that provides it.
The only way I could see it even being a logically..feasible idea, would be if you had a contract set up before hand with a LFS or something..to take the babies..otherwise I think you are setting yourself up for a big heart ache...when you have all these babies and aren't able to properly take care of them, they start getting sick from lack of proper care, you run out of space and you are told to "get rid of some"...and you either have to start culling or they start dying off, because you can't afford to medicate all of them or keep them.
I don't think you want that to be your first experience with breeding. I'm sure you want it to be a happy experience..not a tough luck one.
Why not just keep those Veils for pets, spend $20-30 on a couple of good males, and some nice females...and then breed good, quality betta's. I'm sure your LFS would jump at the chance to have something other then Veils...because they can sell them for more, plus it will bring more people to their shops after people spread the word about "these
new betta's" they saw at the LFS".
Here is a little price Break down for you:
Beanie Baby boxes (12) = $30 (for 190 that's roughly $285)
Water conditioner (1 bottle treats 200 gallons) = $5 (for 7,482 gallons that's roughly $187.05)
Frozen Bloodworms (1 pack) =$5 (for 3 months and 200 fish that's roughly $50)
Heating pads (you can fit 6 boxes on 1 pad) = $10 each (for 190 boxes that's roughly $315)
Total = roughly $837.05 ..before taxes/shipping.
That's just for 3 months, and that's just a few of the many items you will need..not mentioning medications should they get ill, or silk plants, ect.
Just some things to mull over in your head before you proceed with this endevor.
