I rarely market frame sets on C/L as there just aren't any customers for them out there. I either put them for sale here or eBay. I donate off the lesser ones. Not worth the trouble to pack and ship.
Put a WTB ad in the bicycle for sale section of your local C/L. You may get flagged eventually, but you will shake some loose. Certainly if I were in your area (I am not), I could offer you many choices.
