Update my php online invoice software VW

Hello, I have a php and mysql driven online invoice software. I would like it to be updated fixed with the following below. To view a demo of the software, please go to [login to view URL] and use admin/admin as the user name and password. 1) Fix recurring invoices. Every time a recursion happens, a NEW invoice should be generated. To be honest, not quite sure how the recursion works right now. 2) The ability to show all recurring invoices 3) Allow the ability to edit the Site Url to include an S for secure server 4) Rip out the current serial code verification and add PHP Audit code. 5) Give the ability to attach the invoice as a PDF file. They can chose from one or the other or both. 6) The ability to make multiple payments towards an invoice. 7) The notes section and message section currently cut off at a certain point. The ability to add more verbiage. 8) Add a PayPal module for online payments. 9) Get rid of the freeze action. Invoices will then not have to be frozen to be paid. 10) Make the recurrence section more robust. 11) Fix the yearly invoice chart. 12) Fix the code to allow it to be encoded by ion cube. 13) Add private sections to the data entry customization for the invoices and estimates. Meaning, fields will be added to the form to create estimates and invoices, but these fields WILL NOT be visible to the customer, only to the users of the system. 14) Also, forgot one other thing. Need to add support for various currencies, including, the Euro, the Canadian Dollar, and The British pound. So, that makes 4 currencies total including the American Dollar which is already built in. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
