Ordering A Fish

[OrbWeaver]

I am looking for a male Metallic Blue Guppy and am having a lot of trouble finding one. Was just wondering if anyone could suggest a seller they have used and trust I could check out.
I am sorry if this question has been asked before. I could swear I saw this question before but for the life of me I can't find it now...

Thank you very much for your help. I really appreciate it.
