New Firm

A relative of mine wants to start either a Sole Prop. Firm or a Partnership Firm. My request to law professionals is for a very brief outline of the steps reqd to bring into existence:

a) Sole Proprietorship Firm

b) Partnership Firm

I am a commerce student so i wud be able to understand the technical terms. So in depth details not reqd. But i request for the Broad Outline or a series of Steps. 

Thanks a lot.
