i think the only chance you have of meeting 1k is do all the prep work then hand it to a back yarder and supply the paint. dark grey is that metallic. if so your looking at clear as well as a more expensive paint. i prepped a mates escort. every thing pulled apart, primed and sanded. i got him to hire a booth and the dude that owned it at a shop said he would spray it for 280. that job was under the 1k mark but the offer was never extended again. ive always sprayed my own cars. did use acryllic but now use 2k as i think its better. i did once hand a ute to a spray shop as i worked flat out and didnt have the time. again totally stripped primed and ready. they supplied paint and booth and it was 1500. the big issue is your asking profesional shops to do something dodgie for under 1k. as a minimum most would quote 2 days to strip all essential bits, tape,prime sand then add the cost of the spray booth and paint. so 16hr @ 77= 1200 odd plus booth and paint. usually some shops don't use any unkown paint as it could cause more probs. 2days prep from go to whoa is pushing it as these shops put there name on a car and don't want it coming back with faults. let us know how ya go. it pays to shop around alot. also alot of fellas that work behind the counter at the paint stores are painters, used to be painters or are well set up to do back yarders so there worth asking.
