Is anyone selling BN's in Essex?

I am looking to start a breeding experiment with a pair or trio of bristlenoses. I would like longfins or albinos or a mixture. I would like to either start with a group of 4 or 5 juveniles or perhaps an adult trio or pair. My primary concern is finding a local supplier or someone with very good experience of sending live fish. My tanks is probably 4 weeks away from being ready but could hold them in another mature tank if fish are available now.

Let me know please.
