I was thinking about putting a wanted ad on craigslist for freon removal from ACs, refrigerators, and stuff, and I was wondering how much I should offer. I was hoping I could find someone that would trade the service for maybe half or 1/3 of the scrap appliances I get. I'd rather trade than pay cash. Anyway, does anyone have an idea how many scrap appliances I should offer in exchange for the freon removal? 1 for every 2 done? 1 for every 3? Let me know your thoughts. Thanks.
