.info domains are not worthless (.co.cc and .tk domains are)
With that said, .info domains typically carry a lower value then most other TLDs. In the case of the OP, he has a brand-able domain, but not a high value domain. The other factor that goes into cost is age... this domain was registered in November of last year (on my birthday actually).
With all of this said, I would not pay more then $15.00 for the domain at the high point with $10.00 being realistic
To get the most out of your domain or website you need to reach the highest possible ranks. Means more visitors, more sales, more requests and so on, your domain TLD is .info and basically this TLD is used for wiki sites not a normal website so this will let you lose money more to gain. Try to search for better TLD like .CO or something in your brand name so you can get .COM also you need to do better look of the site so you have to design a better layout. In general your site as it is in this situation it will no get you so much money and it worth $xx and maybe $xxx but so much!
