Way too many variables. What shape is it in now? How much body work needs to be done? Are you taking the Bronco to the shop disassembled? What part of the country do you live in? Do you want single stage or a base/clear? What do you want painted? Inside of tub? Engine compartment? Doors? Top? ect.... way too many variables to get a good estimate.
If it's a scuff and shoot, no body work needed, detrimed, just the outside with doors, no top with base/clear then you are looking at about 4-5K in my area which the labor rate is $44. The hard part is finding a shop that will do it for two reasons. One, it's more profitable to work on modern cars. Two, flat paint jobs an be a pain to paint since you have to pay close attention to overlap and keeping dirt out of the paint. You can't buff a flat/semi gloss paint job. It brings the gloss back if you do. You might have to live with some dirt in the paint job.
