I just want to second, third, and fourth the suggestions to cancel this deal, call your credit card company to dispute the charge, contact an attorney who does work with real estate/timeshares/contracts, and talk to a financial planner.
I think it would also be helpful to know more about your situation. Does your $2400 per month payment include your maintenance fees? You must have millions of points, so you should be able to rent many of them out to cover some of your fees in the meantime. I'd also guess that you must be Platinum VIP, so you will be able to rent points at a discount and get unit upgrades and free guest certificates. While you do battle with Wyndham over this, I think it would be helpful to at least recoup some of your costs.
Second, what has Timeshare Answers indicated that they will do to get your money back? I would not give ANYBODY $3000 unless I knew exactly what I was getting for that money. A vague promise that they'll get your money back is not going to cut it. Even the money back guarantee is likely to be useless.
In terms of contacting an attorney, I know you mentioned you already did that. The attorney said the contract seemed fine. I'm sure it would. It's designed to look legitimate. If any/all of these timeshare recovery companies were totally on the up-and-up, I'm sure your attorney would be right. However, people on this forum have seen your situation dozens (if not hundreds) of times. Your attorney likely has never dealt with this before. Scam companies are very clever and creative. If you look at the old thread for Sierra Resorts and Rentals, one poster on that also took her contract to her attorney and got the thumbs up. The problem was that Sierra was a scam from start to finish, so there was no way to enforce the contract. Despite warnings from many on TUG, the post paid $5000 or more to the scam company and got nothing for it. A law degree doesn't grant special knowledge about timeshares and timeshare scams. Only years of experience "in the trenches" will do it.
I would recommend finding an attorney who can work with you on this contract. It sounds like there must have been more serious misrepresentation than usual to convince someone to spend $2400 per month. I'd rather spend my money actually filing a lawsuit against Wyndham than paying an upfront fee company. And as Denise pointed out, even bankruptcy or credit damage might be worth it to get out of paying that kind of money every month. What ISN'T worth it is spending $3000 you said you can't afford to lose on something that is likely to get you nowhere and do nothing for you.
