New here but will be going first and using MM etc. Just after a ballpark $ or gp range

 

I would say that for the 99 cooking skiller the most you could get would be $30, as it isn't a difficult 99 to achieve.
As for the Zerker/RS3 Skiller, I think you could ask for around $150 at most as it is ruined with the 46 defense and doesn't have any combat stats past 90. It would definitely be worth a lot more with the 3 letter rsn and the attached RS3 account, if you had vouches and some reputation.
Good luck selling!
