Total E commerce development novice help required Beállítások

[bining]

Hi

Im looking to start an e commerce site, I have no knowledge what so ever of this. Just looking for basic help if you don't mind
I know I can get and sell the product, but no idea how to get to the top of google and how much this could cost? I know its a vague question as all industries etc will be different.
Website im guesing is 6-7k, not an issue, could sell on e bay but same companies that sell their products here sell them for 40% cheaper on e bay than their own sites.
Any comments appreciate thanks
