I would run different contests on my site to draw traffic. Once I doubled the $1,000, I'd pay it forward to another marketer in need to do the same thing to get their business off the ground.
I would buy some gifts for Santa to impress him and ask for some more thousands so that I can do a business with proper budget.
I will buy a lot of domains and make some sites. If you are talking about starting a drugs reseller business I don't think you will need any real investment but you will have to spend time in jail if you are caught selling drugs. How is that an investment? You going to open your own brothel?
buy something not available in my country from China (something that's less than $20 per piece) ship to to my country sell it
Personally, to be honest with a small amount like $1,000 I'd invest it in some SEO mainly link building.
I will spend half of it on charity and next half will use on my necessities you did not tell us what was your plan
I would buy a ticket to go back to Thailand, live on the beach, become a scuba diver, and then come back occasionally to feel relevant.
