Never been to a detailer, but...
If I were doing your car I would charge you about $125 to do JUST the exterior, this of course depends on the degree of the scratches, might be more....might be less.
The services you should get from a competent detailer should be a hand wash, level the paint, polish the paint and then seal it. Tell the detailer that you do NOT want the scratches hidden with a filler type glaze but that you wish them to be removed.
Finding a good detailer is going to be harder than perhaps you yourself removing them with a PC and the right pad/products.
Wish you well,
Anthony
