Thank you very much for your quick response. I have read dozens of articles
on best practices, but also know in a production environment a good
consultant is never overrated. If you are available through gtalk or some
medium I would like a brief conversation with someone and would like to put
50 bucks worth of time in someones pocket!

You info was very helpful!
