Dan,
I'd like to work in your project. I have plenty of experience in services integration and communication via SOAP. I'm starting my career at Freelancer.com, but I've worked on the enterprise market for more than 6 years now.
I like to do my work right, that's why I liked your project, and hope to be helping you with it. I believe I pretty much understand what is needed and can't think about questions right now, but I can give you my word I will always be open to talking things out even after the project starts.
Feel free to ask me any questions you need about me, my experience or how will I handle your project.
