Authorize.net subscription programming

I'm currently looking for a programming company who can create two [login to view URL] subscriptions for me.? One for a monthly subscription amount and the second for a yearly subscription.? They both have different prices. You must review the existing programming and the way it has been set up and modify accordingly to complete the ARB.? This includes, also subscription cancellation, and modification of payment information as well.? This should be a simple item and you must not delete any existing programming to create the new programming.? Any existing programming will be left in place and commented. Good programming practices are a must with this project and backups of existing pages are required prior to modifying them. This is a very small project to get started, however, it is important for us at this time.? Additional projects may follow. ## Deliverables This should be a simple project for someone familiar with PHP and authorize.net. Please ask questions for further clarification.? When hired, the programmer should review the code and determine quickly what changes are needed so that the ARB can be used and integrated into the web site.
