Fairly straight forward really, strip the old paint back to bare metal either "the hard way" using stripper, scrapers & sand paper. Buying some decent paint stripper like this will help, the DIY stuff is useless.

A different, but NOT much slower option is to strip the body down to its component bits & get it blasted to remove the old paint. Baking Soda seems to be "the popular choice" at the moment, but glass bead or fine sand is fine as long at the operator knows what he is doing.
Your final stripping choice is dipping. NOT one I'd recommend.
Once the paint has been stripped, make good any duff metal (sounds easy doesn't it). Then onto paint.
Etch prime, then a high build primer is a great start whatever you are going to paint with finally a very good flat with 600 or so grit. Your top coat options are enamel (original), celulose (very tricky nowadays & finding someone who can paint celly well). 2 pack, is the easiest to spray & is easily cut back after painting, but benefits from baking in an oven, I have no experience of the modern water based systems, but imagine they will not be far off traditional 2 pack.
What you pay for a decent paint job is a totally open ended question. From £400 for a crappy back street or mates rates job to £5,000 for a concourse special. Most of the cost is in the preparation a lot of which can be done at home.
