Configure and Design InviteX Extension on for Virtuemart

I have the InviteX extension installed on my Members-Only eCommerce site built on Joomla and Virtuemart and need it configured and designed so it has full functionality to invite members through different email providers (gmail, yahoo, etc. and social media). APIs will need to be configured. I have attached a screenshot from a competitors site for review. My invite page needs to look similar but have my site's design look/color scheme. If you need graphics to be coded, I can supply them. No milestones please! I have been screwed one too many times by paying for services that I get and are not 100% complete. Please only bid on this if you are confident you can get the job done.
