What is your dilemma?

Trying to find someone to do it without taking off my head.

The only way to find a good contractor to to talk to people in your own area. Get recommendations from people you know, or call references. Check for licenses and insurance. Talk to and get quotes from several contractors to help you decide.

A 40-60K average mid grade master bath renovation like that requires design work first for the permits. And there is ALWAYS electrical work needed, from an electrician. . As well as plumbing reconfigurations, from a licensed plumber. Plus framing, tiling, demolition, disposal, cabinet making, stone fabricating, and knowledgeable coordination of it all. Your K&B Designer should have plenty of connections to good contractors. Who should be able to start in February or later.

I think you really do not understand the scope of this work so you really need a pro NOW . If you want even a guess from us you need to show what you have with pictures and a to scale floor plan and your idea of budget.
