Redesigning VBA Database application

We're plannning to transpose our Microsoft Access-VBA Database-Project (about 16.000 lines of code) to a more professional platform (php and mySQL? other options?). We want to obtain a highly specialized software product, which is professional enough to sell it in a small market-niche.. We need a programmer, who can translate the VBA-program to a more sophisticated programming language and include a sleek install-routine. At the moment we have no idea as to how expensive this project is going to be, so we don't know yet, if we can afford to proceed with it. ## Deliverables We can provaide a working version of the original VBA-Program as a "working prototype". The prog will have to include a document-generator for writing letters, and must communicate with other Windows-programs i.e. start other programs with command line options.
