Welcome to NP
Congrats on the sale.
No, you need to start again with these.
Try and focus on names that are easier to sell and have a larger end-user base.
First research and read this forum from top to bottom for a few months so you understand what makes a name valuable.
All this below only comes after you have read this forum for a while.
Check out DNJournal.com and Namebio.com to see what type of names sell
Check out expiring lists and see if there is any value in the dropping names.
Email existing owners of decent names and buy 1 or 2 names, you wont know what is decent until you have done your research
Make sure there are plenty of potential buyers before buying the name
Emailing potential buyers asking if they are interested in the name
Don't get greedy when starting out and sell for a reasonable price
Reinvest that profit into another name and then repeat the process.
Don't mix letters and numbers
Avoid long names and dont buy 3 word names
Avoid trademark names!!!
Stick to .COM domains
Avoid hyphens in domains
Avoid hand-registering names that are available, they are available for a reason.
Good luck, hope that helps
