Nice keyword - not so good ccTLD. It's hard to give a good appraisal since ugandan domains are not very in demand. Find the correct buyer and you can get some nice money. The problem is to locate that buyer. Search for 'business' on afternic and you will notice lots of business.xx domains for sale (including business.ug). Asking prices goes from $1995 to $100000! I dont think many domainers would like to buy these domains. Try ebay The only good .ug sale I've seen was poker.ug (Sold on ebay for $1500).
Alex, H2O is correct. This UG is pretty lousy TLD; first, because it's a ccTLD, and second Uganda isn't exactly known for business. Something like business.lu would be much better. If you plan on investing in ccTLD, you've got to think beyound domains and look at history, politics, popular culture, and economy of a country/ccTLD. Best.
There are many perfect domain names on ccTLD that not touched. But business.ug seems to be very attractive for some bank or profit organization in Uganda. Try to sell it for someone personally there (via email or something like that), you could make good sum.
