Just keep on doing what you are good at. If you are smart enough to make 10k, then you should be smart enough to not ask other people in what you should invest. I am saying this only because its in your interest, believe me. Cheers!
Start of with buying a couple of low-earning Adsense websites, see how you like it, and if it's your thing, spend the rest of the money. Also, as you seem good in domains, you could start a forum (more just for fun) and share your knowledge there, maybe it will grow big.
Lol ... if the "financier" (proper term is "trader") is any good they won't be hiring out their services
keep doing what your doing i say. although im very fond of retail businesses, and 10k is more than enough to take a stab at a niche if you can find one.
Think about actually creating a new business - $5K worth of development can do a lot if you have a clear idea of what you want.
I'm not sure if you're going to be successful if you can't properly spell "wanna" right. It's your money and no one can tell you what you're going to do with it. Yugo,
Buy 1 or 2 domains for $10k and wait for years. This would be the safest investment for you as you know about domains. You won't need to be online to do that. Just do not forget to renew those domains.
Buy a high traffic domain , with over thousands of backlinks and it is indexed in most search engines. Invest in the site , make something awesome , sell your product , and keep doing this till your site gets popular and your sales will bring $$$
Website sale prices are experiencing serious deflation. You can probably buy a website that makes $2000 a month for $10,000, which is less than half the fair price. This is unfortunate for the sellers, but a potentially good opportunity for the buyers. You would own an incoming-producing asset free and clear within 5 months, and would be in the money thereafter. Just make absolutely sure the niche will remain profitable for at least a few years -- stay away from luxury products. Good luck!
