Affiliate Marketing Secrets

I have a desire to become a small business owner and even bigger later on down the line. Majoring in business..I’m really anxious to start my own, profitable online business. I don’t care if I’m only seeing 20-30 a month lol for a while, just to know that im seeing some sort of cash flow lies room for improvement to make more money.. I want to know..which websites are the best hosts? Which ones make it easier to sell things? Can i sell there products and make money off them? Affiliate marketing??Etc, etc, etc..I don’t have much money to start..I don’t really know what I want to create my site off of, what products to sell etc. All i know is i would like to sell electronics, tech stuff, accessories, etc. Anything else actually that I could create a profit with that’s not so hard. Ive heard of soo many different sites that I can join and start selling there products and make money that way. Anyone know of the best or if that’s a good idea? Help please

im thinking of writing an ebook and selling it on clickbank to help with cash flow as im a student. Is it profitable though?any experiences? how much can you make realisticly a month? I was gonna sell it for $2 to hopefully increase sales and get exposure but no affiliates will want that so $15 with 50% commision. I will have a website and all.advice would be great
