What will I do?

Train any skill, combat or non-combat, except for dungeoneering.
Also willing to possibly do a couple of easier quests.

How much does it cost?

Nothing

If you're going to post making a request for a service, READ THE FOLLOWING FIRST:

I will not provide materials for you. If you want me to do a quest, you must provide every needed item. If you want me to train a skill, you must provide whatever is needed. If the skill is fletching, you must provide logs. If it's alching, you must provide nature runes, fire staff, and the items to alch.

And I will not make a character for you, you must make it yourself and put it through the tutorial first.

Lastly, I don't train combat on f2p characters. P2p only. I'll train any other skill on f2p.
