URGENT - Subscription management website

Hi, Need a subscription management website where members can ================================= 1. View / renew their subscription. 2. Purchase SMS credits. In addition to above features: => General site pages would also be required along with a CMS => A very small web service interface (3-4 functions) to allow our business software to interact with this site via SOAP. Please see the attached file for detailed requirements. => This project needs to be completed quickly (3 Weeks) and without any delays. => We intend to provide the web design. Do not include design charges in your bid. You can put design charges in your PMB message, we will consider it. => Open source technologies like Joomla, E-commerce Platforms, Forum tools can be used to keep cost and development time down. But proper integration at the site level is of utmost importance. => Bid only if you are an experienced provider with a decent sized team to complete this task. => No automated bids.
