You might want to reconsider what you accept as payment.
Not trying to be a dick, but those 2 names are not 'rare' what-so-ever, and if you are lucky enough to find someone to buy them, the price will be so small that it is probably not possible to use WU for it. And half of Sythe doesn't even own a Paypal, let alone Moneybookers. I also think you can only send/recieve money from US to US accounts, not US to AUS or something like that.
Just accept Paypal man.....as long as you search the buyers history there should be nothing wrong. I have been chargebacked more from other sites than Sythe.
