There are many good suggestions so far
There was/is a poor condition booth off north Cowan ave in Lewisville that could be rented for time used. Definitely not modern by any stretch of the word.
You could try and do a little of your own leg work - but these suggestions cannot be done via the internet or I-phone - to be of real value one would have to get off the couch and ask for information in person.
Go to the county community colleges that teach auto refinishing & see if they would help you out (or perhaps one of their students would). Long ago - I knew a retired pilot that would take the refinishing classes just to work on an old 356 for the facility and equipment.
Try a couple of “Mom & Pop” body shops - and ASK ( don’t call - but show up and ask - yes there is a difference).
Spraying at home is probably going to be your best bet in a make shift low dust / low bug tent with plastic on the floor, lower humidity is on your side this time of year but the lower temperatures are not.
