I highly recommend Matthias Helletzgruber. I had such horrible luck with vWorker until he finally came around one day and bidded on this project. I am very glad he did. He was very respectful, asked questions, and made sure he was doing things properly. He was fairly prompt with his replies and accomadated my desire for him to modify the code to add more functionality.

Good quality product. Very helpful throughout. Am releasing funds slightly prior to full completion. Been true to his word throughout and have no reason to doubt this will continue.
