Actually, ads on CL belong in the "Small Biz ads" under "SERVICES". That's why they get flagged off the "WANTED" section. If you pay, say so. DON"T TAKE CRTs. What to charge? I'd say, start with 25-40% of what you expect to make. You might want to specify what (scrap metal, scrap computers, electronic equip etc) and general area you'll travel to.
