Booking calender for multisite

I need installed a booking system for online reservation and availability checking service for my marketpress multisite. The goal is to have website visitors check availability of properties and make a booking within minute. I have already installed the plugin in wordpress but I cant seem to get it to show in my product page. I also want this plugin to be integrated to the payment function of the site so after the website visitor makes a booking he/she will be taken to the payment section to make online payment via paypal. I will configure the perimeters in wordpress dashboard you just have to make it show in my products page and integerate to my payment system. Please ask more Information. Source: [login to view URL]
