Greetings. My name is Jeremy Trammell and I represent a group of developers and designers in Portland, Oregon, in the U.S. We have extensive experience with Javascript as well as with the Arduino platform. I'm a little confused by your RFQ, as you state at the top that you are looking for consultation, not assembly or testing, but at the bottom you specify a list of deliverables which would generally be impractical without a development environment. I have estimated our bid based on providing some consulting time, rather then developing a deliverable solution. If you actually want us to develop an end to end solution for you, I'd be happy to update our bid accordingly. With regard to the actual implementation of your project, have you considered the Raspberry Pi? It's cheaper than most of the Arduinos, and would allow you to run the web server directly on the same board that was driving the LEDs.
