Hi Haris,
Paying you SaleHoo membership gets you the help you all the assistance to learn the business mate, you don't need to give anyone 50% of anything.
Just start firing questions and we'll return fire with some answers and as much advice and we can muster. It's always easier to respond to question rather than just ramble on, as our assistance can then be more tailored to suit your exact requirements.
I think a good place to start is what sort of products you are considering selling, or do you have anything in mind at all?
