I faced a similar issue with mine. In the end I decided I wasn't after a car that looked like new and I'd rather feel I can get on with running repairs and maintenance without worrying about a showroom finish.
I bought a compressor and a cheap spray gun and am learning how to spray paint. Doing it bit by bit doesn't make for the best finish, but it keeps it on the road and looking reasonable.
A bodyshop will charge towards a grand just for a basic respray so it's well worth having a go yourself. The worst that can happen is that you end up having to send it to a bodyshop after all.
The tip I was given by a local bodyshop is not to remove anything you don't have to. If you were doing an concours restoration you'd take everything off of course. But for a basic paint job the less you remove the less there is to break, lose, go wrong etc etc. I must confess I wasn't convinced, but I'm beginning to see that it makes sense.
If you do it yourself you know what's what and if some rust appears in a year or two then you know you can sort it out again.
Yesterday I started on the boot which was the last bit looking a bit too scabby

It looks better on the photo than on close scrutiny, but it's good enough and I'm not worried about chips or scratches. The more I do the more confident I'm getting and it's a lot more satisfying than paying someone else to do it.
