Building VBA functions related to fixed income derivatives -- 2

I'm looking for someone who can write VBA code for finance problems. I need someone to assist we with a project that lasts from June 20 (10 o'clock central European time) until June 22 (10 central European time). It could be for a few hours or longer. The project will be about building a VBA function to solve problems related to fixed income derivatives. For example to calculate forward rates, pricing of caps, floors and swaptions, CDS pricing and so on. Feel free to contact me for further information.
