Any surgery costs money, and $7000 doesn't strike me as all that much. For a little more than you paid, I got a consultation, about six or eight follow-up visits, a postsurgical truss, some free samples of scar reduction stuff, some medical supplies (including the first dose of pain reduction meds), some free promo items, and the actual surgery. For the surgery, I needed the skills of an anesthesiologist, the surgeon (who had something like twenty years of surgical experience), and, I'm sure, at least one surgical nurse. I also took up space in their preop unit and recovery unit. Part of the package was a complete revision under local anesthesia, and the surgeon's fee was completely waived for that, although I had to pay an additional $300 for the anesthetics he used (I knew about that up front).
If you want an Earl Scheib surgery, by all means find someone who will do it for $29.95. But you probably won't be happy with the results unless you are serious about just chopping off the things and leaving it at that--and I don't think any reputable surgeon would do such a thing. Still, have you shopped around? I hear that Garramone is pretty cheap, but if you come from out of the area, you will likely make up the difference in other costs, such as travel and accommodations.
