How much are you will to spend? Sure you can do it for cheap but if you want
immediate results you are going to have purchase some software. Remember it's a
business so consider it an
investment.
If you have some money to invest than I
highly recommend you purchase either:
$197.00
xSitepro
$295.00
Semiologic - I use them both but I now use Semiologic exclusively on my cluster sites.
VERY cool Wordpress CMS and
uber search engine friendly.
Also pick up a copy of
Adsense Empire.
