Mission Resort Sales time share broker of Las Vegas (by Lance C.):
How did you learn about this company? Was it an unexpected telemarketing call? If so, then it is likely a scam.
Is this company claiming that it can sell or rent out your unit for scads and scads of money/ Then that would be the second element of a scam.
Chances are they will say they have found a buyer (which they haven't) who has agreed to pay a princely sum for your unit. Then while you're paralyzed with excitement and not thinking rationally, they will hit you with "Oh, we just need you to pay a fee/tax to complete the deal." The fee/tax might sound legitimate but it's not and it's a scam.
Maybe you can supply more details about their offer to confirm our suspicions.
