Don't give up. That is the key. So you lost $6500. That is in the past now. There is nothing you can do about that. What you can do is learn from your experiences and be smarter with your money and your purchase decisions.

Several of the ebooks give detail on very honest businesses.
Some good businesses you can from India in my opinion:
1. Import/Export - this includes e-commerce, selling on auction sites, brokering, B2B, etc
2. Offer Web services. Includes SEO, article writing, web design and graphic design, coding, email customer service, social media and video marketing services.
3. Affiliate Marketing. Includes having a blog and using social media and video to get a following and an opt-in list and in turn sales. Affiliate Marketing can be done for very cheap if you know how to and their are tons of books on this. Using classifieds and forums also helps.
4. Start a blog that is informative, grow a business out of it
5. Start an internet marketing business - this can include ppc, niche marketing in different niches, affiliate marketing using clickbank, coaching others (such as offline businesses on how to use the web to grow their business), selling books on forums like digitalpoint and warriorforum.
These are 5 different great business ideas that all take a lot of effort and which ever way you choose, you have to treat it like a real business. If you want to do business online you have to learn the ropes and you have to work on it each and every day. I would say do what you enjoy. Have goals and reach them by using time management and organization skills.
Don't let information overload kill you.
There are several illegal business models too like selling replicas, selling marketing products illegally, illegal dvds, cds and software, and of course all of the blackhat stuff. I don't necessarily support all this but I understand how tough it can be to get started and make money.
