Since all upfront fee resale companies (that charge in the hundreds/thousands of dollars upfront) are scams, do not for any reason give your credit card number to them. If they can scam you for your credit card number for the upfront fee, they can use your credit card number for other fraudulant purchases as these people are, in essence, thieves and should be in prison with other criminals.
Remember this post when they call you with all their lies ..... DO NOT EVER GIVE YOU CREDIT CARD # TO UPFRONT FEE RESALE COMPANIES.
