DIY quality paint job
My dad and I painted my 71 Corvette in our garage. It didn't turn out too bad, the big issue was that it was a single stage paint. This made it hard to buff out since you got into the color real quick. The other main issue is keeping the dust down to minimize overspray. Throwing some good sheeting down would probably help. The overspray came off pretty easy with a simple soft buffer and some time, made it look a lot better than I thought it would, not show quality by any means, but looked a lot better than all the touch up splotches it had before. A lot of it really just boils down to your equipment and dedication. There's a place near me that actually rents out paint booths for sanding or painting, you might see if you have one nearby. The one around me seemed reasonably priced, something like $200 a day I think with different rates for long term or short term.
I know the pictures aren't too close so you can't see any real detail, but it's a good parking lot paint job and holds up okay under scrutiny. We had big issues with water in our compressor, needed a much better dryer to keep the gun from dripping in a few places.
