Hello,
I'm a Network and System Administrator. If your site is hosted on a VPS or dedicated server, and you can provide me root ssh access and mysql root password, I can optimize it so your site will load faster, but I can't help you customizing the site, as I'm not a web programmer. Please see my feedback to evaluate my previous works, and shoot me your reply if you want to talk about this further.
Regards,
Aroel
