How to find a good artist that specializes in tattoo sleeves?

My current artist is amazing don't get me wrong but his ink he used on my ribs wasn't of the best grade also he doesn't do sleeves ever really and if he does there never in all color I can't ask him cause that would be weird and kind of rude I live in Oklahoma tattoo parlirs just became legal here years ago so finding a quaility artist is freaking hard mist shops on the streets here have awful artist most there work is very amatuer to say the leaset
