Affiliate Marketing Secrets

I have a business idea which could be of value to any dating website entrepreneur.
Where can I find on the internet a online dating business entrepreneurs forum, or find dating website entrepreneurs who would like to collaborate on a newly differentiated dating niche?

I have an idea for a women’s bra line and I’d like to start delving into making this a reality instead of just a general notion. I know the niche I’d like to fill, and I would like to just do this as a small business from home, selling the pieces via the internet. The thing is, I’m only 19 and have no background in design or any idea where to start in producing quality bras, nor which manufacturing companies to look into. I’d like to find a way to manufacture a few designs inexpensively, rather than hand-sewing or anything like that.
Basically, does anyone know of any sites that might be helpful research areas for my business idea? I’m doing research on my own, but it’s always good to check with others who might know better where I should be looking. Thanks!

I’m a web and mobile applications developer. Can anyone suggest ideas for a good software as a service application? What is a problem that people/business in a niche market encounter that can be solved by a web or mobile application?

Admittedly I’ve no experience in business at all, but the idea of having your own business – being your own boss – sounds an appealing one. How do you come up with a decent idea, though? Is it all about looking for a niche market or doing something established already? Are there any surefire prospects or is it all hit and miss? Anything worth trying?
Thanks.
