When sourcing an installer always ask for references, get pictures of work, and ask to walk through a completed job if possible ( often times you can ask the references if you may see their completed project they are more than happy to) cabinet resurfacing is good option if you want to maintain a stain grade product.

Also if your getting water stains in high moisture areas like bathrooms install some strong exhaust fans.

I put 18k in materials I repainted the interior , replaced the old iirrigation, put up shade screens over the pool and lounge area in back yard, repainted and stained the kitchen and bathroom cabinets, replaced the kitchen countertops, replaced the flooring in both bathrooms and walk in closet and finally put a new Hvac and heater in.

This year I have it earmarked for new staining - so I expect to finish the year around $11,000 in profit or so.
