From someone with no vouches? Nothing. Literally, this type of account is so valuable that any person with any common sense would know that it is very high risk to purchase, definitely with a non-refundable payment such as RSGP.
You would have get low ball offers that would be almost stupid to accept. With some vouches, this account is easily $1000/1Bish, but you would need a stupid amount of vouches to even make anyone consider buying it.
Maybe Player Auctions will serve you better in your goals, but on sythe... All I can say is, good-luck!
