Hi
if..... your names are great, fantastic, top tier and all that, then you would have received tons of emails and phone calls already
if...… your name are pretty good, decent, to alright, then you still may have received some offers
if..... you just registered them yesterday or within the last 30 days and they are not .com, then you're in the pool with a whole lot of others, wanting to sell their names.
still you can list them for free at:
sedo.com
uniregistry.com
afternic.com
perfectdomain.com
bodis.com
fabulous.com
voodoo.com
parkingcrew.com
undeveloped.com
etc.
keep in mind that each has their own TOS and service fee's
some pay ppc earnings, some don't.
you can also create your own sales page or sales site
you are free to decide for yourself and free to do your own research.
make good use of that freedom.
Good Luck!
imo...
