I personally just want to charge $20 once for registering them their domain and then put their contact information in the whois information. I would let them renew their domain every year on their own. I don't want to charge $20 every year for each client
Also, what if you charge them for this domain registration service but then you can't find "theircompanyname.com"
because it's already taken by someone else? Do you go for the .net? Or refund them?
What are you thoughts?
