Depends on the shop but you're probably looking $3000 - $5000 to have just repairs done, parts replaced. (IF there's no additional frame damage under there... Someone needs to pull that fender and really look at the unibody)
You should have the whole car painted at the same time = more $$ than that... Need to find replacement parts for hood, fender - they'll cost more to repair than a finding replacement (the hood is beyond repair by any sensible measure). Then of course it's also missing quite a few front end pieces - some could be ignored if you used an aftermarket air dam instead of the stock lower valence pieces. I probably have most of the parts you would need - if you wanted to drive to Phoenix. Unless it's a ****-of-a-deal, you should probably keep looking if you can't do much of the work yourself.
