If I get your question right. It seems you are looking for a business to start online with $10000 right?
I have these three top business ideas you can tap into;
1) Drop shipping
The basic idea behind an
online drop shipping business is that, as a small business owner, you don't have to maintain a large inventory (or any inventory whatsoever) of products or handle any delivery to your customers. That eliminates the financial cost and risk of having a warehouse full of stuff you might not sell, and the hassle of arranging to send orders all over the country or the world. In fact, you don't have to manufacture or store any products at all.
2.) Affiliating marketing
Affiliate marketing is somewhat similar to drop shipping but with some key differences. With this e-commerce model, you again don't maintain an inventory of your own products, and you don't have to worry about shipping products to customers.
Basically, you
pick a profitable niche for your online business, and then you find an affiliate partner who has products available in that niche. Some of the most popular affiliate sites are Clickbank.com, Amazon.com, and CJ Affiliate by Conversant (formerly Commission Junction). Between them, they offer just about any
digital information product (like ebooks, audio files, video files) or physical product you can think of. Many big-name companies and brands like Wal-Mart and Home Depot run their own affiliate programs.
3.) Online store
You can also start your own online, like Amazon, eBay etc.
I hope you find these ideas helpful.
