Good CMS for backend... from $300 to $5000, make sure it does automatic updates daily.
Nice desings for tour $500 -$1000 / tour
Ad material, banners, galleries etc. $1000 good start up set.

...plus lot of other things. Such as affiliate program back end... from $1000 - $5000 (If not using some billing company provided system)

I guess minimum $10.000 you can get it up & running without affiliate program. Plus another $10.000 for extra content within few months. Sure this is not exact forula... some say you need $50.000 some no way under $100.000 some say just $1000. Large variation!
