Pardon my ignorance, but what exactly do u mean by reg fee? :S
Also,wont sellwheels make sense to car resellers etc?
Hire priests returns 3230000 results on google..could this be of value to sites that may want to offer priest services for occasions like marriages,cremations etc?
Bratrends returns 5,150,000 results.. could it be of value to the gashion houses/lingerie industry that is doing great business on the internet?
Reg fee means: The price you paid to register the name.
SellWheels might be worth something if you developed the site with wheels in mind. I see that you are new and just registered these names. I would tell GoDaddy to cancel these names and take the $80 you spent on them and buy a nicer name or maybe buy a nice LLLL.com. (L means letter)
Alot of new domainers find hundreds of names that sound good and end up wishing they would have never bought them. Read and scour Namepros. Figure out what names sell, and go from there. Also use the tool at estibot to get a rough idea what names are worth more than others. The appraisal tool is not accurate sometimes, but it can give you a better idea on names that might be worth more than others. Try and find a name worth over $1000 with this tool. It is very hard.
