Project: webhosting billing solution

Dear bidders, need a billing solution as simple as possible for a hosting company. PHP and Mysql based. Have to be simple because we need to extend it later in many ways. Would like an already working solution. A good sample of what kind of tool we are looking for is [login to view URL] It should allow purchase multiple domains and associate hosting plans and dedicated servers to that domains, and other kind of products services. Must be template based, Smarty or any other one. All strings must be easy to localize, trought external files for multiple language support. Multiple payment ways: 2checkout and wire transfer, but more will be added later. The admin zone should display orders and customers. Manage categories, products/services and email templates. Get monthly listings about recurring charges to be done, will not be done automatically in the first version. Please take in account that payment will be done when the project is finished and installed in our servers, via scriptlance or paypal. You have to setup plans, domains and needed emails to allow us look the whole system working. We will agree for a certain deadline, if you meet it will get a prize of 25%, any day passed will rest a 5% from your bid. We want full rights to change or resell the project, you can resell it also. Please provide link to your billing solution and logind details to the admin zone. Have to insist, please as simple as possible, only need a solid solution to extend it later. Regards, Pepe
