I need additional funding for my sports management company.  One option I am looking at is to sell some shares to some venture capitalist (or angel investors / silent partners).  I would like to know how do I go about it:

   1. how do I value my company (less than a year of operation)?

   2. how do I value the contribution of the new investor?

 

Hopefully, I'll just give up a maximum of 10% share of the company.

 

Would appreciate guidance from experts out there.  Thanks in advance.
