Well if your going to try and fix it yourself you might have your work cut out for ya

the rear bumper is cake, that will just bolt right in there. You can probably find a replacement for 150-200 that isn't made by ford but will have a good fit. We use keystone at our shop mostly and never have any fitment troubles.
Heres one for $180 still under half of fords prices I bet.
The lights can be found online heres one I found for 44.00 dollars,
Here
Ebay and junkyards can be good places to scavenge parts also, however you will find they want close to what these above are going for.
Now for that quater panel that will be the tricky part, it looks like you could massage the metal back into place and put a skim coat of plastic filler (aka bondo) If the bodyshop does it they will probaby just cut out the spot welds on that quarter panel and replace it, as it would be faster/cheaper than spending time straighting it... as far as prices, it really depends on the area where you live, getting it done in LA will be allot more than doing it in a small town. to give you an example, the shop I work in charged 300 to fix a few deep scratched in a minivan bumper, painted prob 1/8 of it and blended the clear in. I would imagine you will be paying around 1000 in labor to fix that, mainly because of the quarter panel, plus parts/materials maybey around $2000-2500 total, but that will really vary. You can get a maco like job that 70% of the people wont be able to tell the difference for prob. 1000 or you can spend allitle more and repair it so no one but you can tell its repaired.
If I where to do it myself at home I could get away with 75-100 for materials and 224 for the parts listed above, but there would be alllooota work to keep ya busy.
Hope this helps ya some let me know if ya have any more questions.
