I've found that some time ago you bid for this project: http://www.freelancer.com/projects/Java-Matlab-Mathematica/MatLAB-web-deployment.html . I hava a very similar problem - a matlab application with GUI which I want to deploy on my website. I have my own server (apache on ubuntu) but unfortunately only available in my local network. My application basically reads a file selected by user, analyses it and produces some graphs and spectrograms. It's not very time-sensitive but the faster it's done the better. My budget is around 100 USD.
