Hi there!
I read through the job details extremely carefully and it sounds like you are going to build desk app with flash.
I have worked on similar projects to what you are looking for, and I am confident I can exceed your expectations.
Try defining the flow of how your customer is going to use the website to fill the business need you are fulfilling, you have to wear the shoes of your customer and think like him. And these are the actual risks when you handover your project to someone who is not good at these things.
I can ensure you the best quality of work and revise until the work is fully satisfactory.
Looking forward to your response with a ray of hope.
I will work as a partner, not just a vendor.
Best regards,
