Getting traffic for leads is a big, lucrative topic. However, TrafficForLeads.com probably isn't quite right for a brand name. Somebody still might buy it, though -- anywhere from $100 to low $x,xxx if you're amazingly lucky.
ModernSculptures.com would be excellent. As a .NET, it has less chance of a sale and would also sell for less. Same odds as the other one.
AuxGen.com is a catchy name. Don't know what it's for, though.
MappingMemory.com likewise. Maybe for neuroscience. Maybe for computer engineering. But I'm not exactly sure how. A book title? If so, then probably $100 to $2,000 maximum.
These are all difficult to sell.
Opinionist.info has no value. Opinionist.com might. But it's not a real word. And .INFO is only valuable for important real words usually.
Let me know if you'd ever like to try to sell domains about Dubai to other people in Dubai.
