Im Back ;d

Hey guys, i lost all of my runescape accounts awhile ago so im back to try to get another account. Im not sure how much this is worth to anyone but I play world of warcraft on the gilneas server on alliance; I have about 270g and about 500g more worth in items that im working on getting into gold, Im not selling the account im just trying to get a runesape account for the gold and items that I have. So could someone give me some tips on how much this stuff is worth?
