Looking for channel letter wholesaler

Does anybody have a recommendation for a channel letter wholesaler. We have one that is well priced but somehow manages to make a crappier sign with every new order. They recently expanded and training was their excuse for a while which is interesting because now they take even longer than before to finish. So we are paying having to deal with terrible paint jobs, lackluster attention to detail and longer wait times. Can't name them for fear of them seeing this and doing even worse...

 

Thanks to everybody for the suggestions. I have contacted them all and am now waiting on who has the best price.
