I dont pay anything since i do it all myself, but for the sake of posting, here's what i usually get for things:

prices include minor prep work (beadblast, wash). If more is needed then prices should be adjusted accordingly. Prices do not include special effects (flames, etc...). Powders requiring multiple coats (base/clear, base/mid/clear) add $5 per step.

Control arms $50/pr
Air cleaner (carb) $30
Alternator housings $30
Brake drums/calipers $50/pr
Brackets $10-$25
Carbs $75 (much more prep work)
Carb intake $75
Large tunnel ram $100-$150
5.0 upper/lower $100
4.6 2v upper $35
4.6 4v complete $150-$175
Oil pan $40-$50
Pulleys $40 for a set
Spindles %50
t-stat housing $20
5.0 Timing cover $40
Trans pan $25
valve covers $50/pr (4cyl $30)
water pump $40

This is a short list, and is definitely not set in stone. There is definitely a "friend" discount, etc...

edit: ricers are charged double as the powdercoat will actually add up to 20 rwhp. outrageous colors such as kawasaki green and bright orange are charged to ricers at triple due to the massive amount of rwhp those colors give.
