Hello friends!

I am new in Small business forums. I need some help. Me and my best friend are graphic designers and we want to start our own graphic design firm from home. I have a question regarding the share of profit that each of us will get from the business. Actually my partner will mostly be involved in finding clients(both online and otherwise), getting works from them and doing business dealings with them. And I will mostly be doing the actual work, that is, making the designs for the clients. So my question is how are we going to share the profit between us? Will it be fifty fifty share? Will I get more as I will be doing the hard work(designing) and my partner get less as he will be doing the soft work(hunting for work and business dealings). To be precise, how shall we divide the share? I am confused. Please help.
