Simple Wordpress Plugin

We are in need of a plugin for wordpress that will allow members to pay by SMS to get access to post/galleries on the site. User should be able to register for an account and to gain access to a post/gallery they need to pay with SMS - and then they will have a time-based access to that gallery. The siteowner must be able to set price for each gallery, and see sales such as total sales, sales per image and possibly more easy statistics. This does require OOP programing in PHP and should work for the current stable Wordpress version. I do require access to the full code before releasing any payments, to make sure that the script works the way i want it too. If the job is well made, you will be offered more job with higher payment! If you have skype, make SURE you post it in PM for me, as Skype will be our way to communicate!
