Cart66 Rental extension plugin

We need a Wordpress plugin developed to add rental feature to Cart66 plugin or any other ecommerce plugin on wordpress. That is pretty clear as it is. There should be reservation on products and users just rent for a period selected from a list of periods (2 days, 5 days, 10 days etc.). Do not copy paste your message. Just start your PM saying "I know Cart66" and explain in detail how you will do it technically. The one with the best response gets it. I don't care about your past random wordpress sites. I only care about your Cart66 or other ecommerce plugin experience on wordpress and your plugin development skills.
