I have stained kitchen cabinets and want to paint them white. I've gotten about 4 quotes, but each company has a different technique. 1st Painter said they will sand, 2x Primer, 2x paint, clear coat. 2nd Painter said they will sand 2 coats primer, 2 coats Benjamin Moore Advanced Paint. 3rd Painter said sand, 2 coats primer, 2 coats paint. 4th painter said 1 coat primer, 1 coat paint.

What is the proper way that will ensure a beautiful cabinet that will last and not scratch. I've gotten quotes all they way from $1600-$5700.
