When I do a dining room set I price according to how I do the work. I never compare myself to the work or price of someone else. The first thing I do is dismantle everything. The chairs all come apart as does the table and all cabinets. Each piece is stripped by hand, sanded and repaired by hand. When it goes back together every inch has been detailed and better than new. Everything is refitted, re-glued and the structure is solid. I say it all the time "this came out better than new" and I live by that standard. The finish coats I use are proven and usually picked for the environment the piece will serve. Protecting the work is important.
So this should give you some idea of the things you should consider before having the work done. Don’t be afraid to ask the questions or getting a quote. It doesn’t mean you have to have the work done today, but it is important to educate yourself as custom work of any sort is an investment.
