Affiliate Marketing Secrets

I have absolutely zero experience in running a business, but I have got my head on my shoulders. I left school and worked for a year as a waitress in a top London restaurant, I got to see a fair bit of the business side of things and I’m great with people. If I’m passionate about something I can be very driven. I’ve just spent the last 6 months living independently in Egypt and doing my PADI Divemaster course.
I’ve recently had an idea. The place where I live out here is a small but very colourful, lively coastal town. It’s touristed but it’s not completely ruined by it. Just about the perfect balance. All kinds of activities and sports take place here; windsurfing, kitesurfing, diving, quad biking, wakeboarding, rock climbing, free diving, etc. I’ve noticed that there’s a niche here. No one’s ever packaged these things all together and served them up on one exhilaratingly tempting plate. The divers don’t really mix with the windsurfers, half of the people out here probably don’t even know about things like the rock climbing because it’s so poorly publicised. I want to take everything this town has to offer and put it all together in customisable ‘package holidays’ for people wanting to have a fun, active time and meet like-minded, fun-loving people. You could pick and choose what you wanted to do and then at the end of the day there’d be a group event like a meal out or a barbecue. It’d be a great bonding experience and give people a chance to step outside of the box and try things they’ve never given a go before. I think this idea could really work, and as my dad said the ‘overheads’ really wouldn’t have to be massive, all it really needs to begin with is a website and an office. I’m getting very intrigued by this whole idea and really want to pull it off. What do you guys think? Do you like the idea? How would I even go about all of this? Any advice really appreciated.

So i have a black top and i’m thinking of matching it with this skirt

The skirt is kinda poofy when i wear it. i mean it’s not tight or fitted, it really flowy.
would it look okay? Also i’m thinking of pairing it with silver pointed flats. http://www.whatapair.com/wp~aspx~iid_MIA-HEPBURNSNAKE~dim1_LTR~dim2_Silver%20~pw~itemDetail.htm
I’m just thinking the skirt would look too casual and i wanna work with things i already have so, that’s what i threw together

I’m thinking of starting an online biz which focuses on two main themes – music and history.
Do u think this is considered a niche biz idea? How marketable or profitable and well-received would this idea alone be?

I was thinking of being an affiliate marketer for this product, but I need to know if it really works for men and women. It is supposed to help grow their hair back.
