Yeah it's a tough situation if someone doesn't have the time to do it themselves (rip out the tub and wall kit and install a new one, and then mud it nice into the wall, just finding out what kind of corner bead they use was hard for a DIY person like me. (they make super wide corner bead type plastic you can use to rough in the acrylic or fiberglass tub and shower walls). It took me a long time to get it all done myself but luckily I have a second bathroom like most people do.
Where I live in my part of Florida, NO ONE who does decent work for kitchens or bathrooms will do a small job and they quote very, very high because so many cash buyers are moving to Florida, or buying the homes to rent them out.
I'm very lucky in that I have more time than most working adults, so I use my time to do my own repairs which is good because I don't have enough money to pay the insane quotes you will get for what would only take a professional 1.5 days at most to do.
