CMS System Experience? PHP/MySQL Web Programmers?

This might be a shot in the dark, but I wanted to see if any of you reading this have a lot of experience (3+years) with the various open source content management systems (CMS) for websites, and programming in PHP with MySQL databases. 

At SikhNet we are in the process of planning some major changes and need some advice from professionals who have experience in this area. If this sounds like you….please do send me an email with your contact information and let me know some of your experience, so I can get in touch with you.

 Thank you!
