Price Check: level 89, good pking account, 99 fletching, 90 range, 74 crafting.

hi guys, im new to this site,i have an account i stopped playing on and i was wondering how much it would go for on here (in rsgp) since it has some pretty decent stats (99 fletching, 85 str, 86 mage, 90 range, 74 crafting), its a fun pking account,
heres a picture of the account's stats and bank





i also have 1 question, how would i go about selling this account? this is my first time doing this so im not sure, would i need a middle man or something?

thanks
