application upgrades

Based in California, I have an application that creates pdfs and emails that offer mortgage loan choices to borrowers. There is an Editor, Loan Library, Image Library, Settings, and other components. We use a method similar to mail-merge, to personalize and individualize letters and emails. We wish to add the additional capabilities, fix bugs and update databases. Knowledge required LAMP, Linux-Apache-MySQL-PHP. Application is hosted by Amazon AWS. Knowledge of Excel and Amazon AWS is required.
