Questions about staking/coaching

[tonic]

here is the deal:

Me and a friend are going to play in all the low level buy-ins of the spring championships of online poker on Stars. He is paying for all the buy-ins but i will be playing the majority of them. The NLHE. Fixed Limit Holdem and the 5-card draw one.

Since he is paying the buy-ins and will play a few of them on is own. what would be a good percentage of the deal? Im also going to have a coach when i play on Skype so how much should that person get as well? I know this is a crazy scenario but im just trying to get help with it. I was thinking 35-65 with my backer on the ones i play in and out of my 35% percent giving the coach 15%. does that sound about right?

Or should i just leave the coach out and play this on my own? Once again I know this is a crazy scenario so any feed back would help.

Thanks for any advice.
