Welcome to TUG!
I am not familiar with that particular company, but typically, the next step is that they will ask for a large upfront payment to list your timeshare. After you make the payment, the "seller will back out" and that's the last you will hear from any of them.
With the economy the way it is, people are dumping nice timeshares on ebay for $1, because they can't afford to travel and they can't afford the maintenance fee. If this company has a buyer willing to pay thousands for your timeshare - be VERY suspicious. Right now on the resale market, the top dogs like Starwood, Hilton, and Hyatt are selling for 50% or less of retail, the mid-level resorts for 10-20% of retail, and the bottom resorts aren’t selling at all.
Here on TUG, we don't recommend paying a big upfront fee to a reseller, because once they have your money, they have no motivation to actually SELL your timeshare - why bother? They already have your money!
If you have to sell your TS, here are some links that might be helpful, but if you can hold on until the economy improves, or if we can help you learn how to get more out of your TS, you might be better off.
