Yeh I wouldn't Reccomend spraying it yourself dude, unless u have painted lots before, Best bet is to get as many bodyshop quotes as you can, prices will vary Huge from company to company, a guess would be for full respray vetween £600 to £2000.
Try to visit smaller bodyshops as well as larger ones, as Insurance bodyshops charge loooooooooads more than smaller places!
Also pop into a local factors and ask for reccomendations on local places.
We recently did an Audi TT that had Acid tipped over it

and charged them £1800 for full respray inc primer paint etc.. No panels were dented etc.. so easy job, but cost him a bomb!!

The paint world is the biggest rip off going if im honest mate, Factor cost of the paint to spray a whole car in say white can cost as little as £50 then to spray it maybe a few hours actual work then boom done... And you the customer gets charged £1500 ??
make sense??
I dont feel so bad tho as its not the genral public we do most are work for its the insurance company's!!
