Joomla EXPERT - Virtuemart -Paid Registrations

I'm looking for a Joomla expert to consult on customizing a new joomla site. I'm a programmer, but new to Joomla. Rather than learning as I go and digging through forums, I would prefer to speak with an expert one on one. This is what I am looking for: Advice on configuration for optimizing site performance and security, along with recommendations of useful/necessary components/extensions. Advice on how to approach paid membership along with collecting additional fields at the time of registration. Also, I am looking for advice on how to best handle paid events. Finally I am looking for advice on customizing virtuemart. I need you to be a good communicator and fluent in English. I need you to be available via google talk, AOL, or yahoo messenger. **** At this time, this project is only for me to get advice from you on the best way to handle the questions I have. I may ask you for a quote to do the work once I get an idea of what is involved. **** Please PM me for more details - I wont respond to bids only.
