Pascal Compilier in Javascript

I have a "Pascal subset" compiler + interpreter written in javascript based off Wirth's PL/0. It is approximately 2000 lines of JS. Currently it only accepts "var" declarations, and treats them as integers. I would like to change this to using ints, reals, & chars. Price is negotiable and if you would like to look over the code before accepting, let me know. I have additional things I would like to add, such as multi-D arrays, and pass by reference. I am willing to spend $500 if someone can implement it all in 2 weeks. (can break up into smaller tasks like this for smaller payments, and less risk). Any extra info needed, just ask.
