Affiliate Marketing Secrets

I have recently written a book that I would like to sell online as an ebook. I am looking for advice on what steps to take in building a website to sell the book on, how to accept credit card payments, and information on how to join an affiliate program. I am looking for something I could possibly do through a site like go-daddy maybe? I am not exactly sure how to begin. Please help. Thanks in advance for the advice.

If one of my parents works at the university or affiliated institution how dos that alter my chances of being accepted?
Thanks in advance!

I’m going to be a freshman this year. I am going to major in biomedical engineering and I really want to study abroad. I don’t want to go during the year because I want to focus on my studies, but I would like to go to Germany or France next summer. My school only offers business summer courses abroad and year/semester programs. So I was wondering, since I have a lot of unused scholarships, if I could use those for a summer program abroad, which is through a study abroad/ foreign exchange program (not affiliated with my university).
They money I get back every semester from left over scholarships I am saving, but it won’t be enough to cover even a fourth. I do have other scholarships, which if I do not use, then I do not get the money at all. So could I use those scholarships, instead of letting them go to waste.
I’m going to ask when I go to school, but I was wondering if anyone else might know.
Thanks in advance

Is it very difficult to get one?
I don’t want to get into trouble.
Any advice is very welcome.
