1 Grand eh... that can go so quick... any startup site can cost a lot more than a grand and will take awhile till you see some good returns...

wish you had an existing site scenario then i had better suggestions...

If you wanna go new... buy a SOCIAL networking packaged solution that comes with everything and start off with that... it can run you 300-500... then buy some marketting $300... then do a simple design from the default template....
