If you want a CMS your best bet is to use WordPress. I’ve been dealing with programmers and designers for the last 8 years and I can honestly tell you nothing that ever starts from scratch gets finished.
And the other problem is that there is no way that five programmers working on your project can compete with millions that are working on the WordPress project.
You can have it installed and working in under two-and-a-half minutes.
And the really cool thing about WordPress is not the ease of use, the fact that they rank really well, or that people can leave comments. The really cool part of WordPress is all the themes you can easily find.
