Opencart Gamification Reward System

I want to add a reward system to my Opencart. Needs to include points for: Facebook Likes Tweets Newsletter Sign Up Registration Referring a Friend Purchasing a product Facebook Shares Google +1 Shares Any shares Points will equal discounts so need to be able to control and set levels. Also need for emails to be sent to people once a new reward has been achieved. I need to be able to add our images to the emails and rewards. If you have experience doing this then please send me a demo account to test or examples of your work. I will only work with experienced Opencart and Gamification individuals. Need someone who is reliable at replying to emails or skype if needed. Keen to start project soon. Nick
