Improve my knowledge without seminars

Is There Any Site Where I Can Buy Any Useful Books? Or Is There Any Site With Hints About Businesses?

Don't buy a business book yet! check out the business link and also there are many websites which are free and can provide very helpful information on more a less every topic possible. The best knowledge possible can be learned from experience, that is invaluable.

For the business link, just google it. In my eyes its the best resource for learning the foundations.
