Your project description is very well written and I am confident that this is something I can complete in very little time. I have placed a bid at the lowest possible price because I am new to the site and I am more interested in building relationships and adding positive reviews to my profile than I am in money.
I have significant experience in building Javascript forms from scratch, as well as editing and troubleshooting previously built forms. I am an excellent communicator and can guarantee that if my bid is selected, not only will you will be completely satisfied with the end result, but the first submission will be exactly what you are expecting.
The only item requiring clarification would be the statement under the Other requirements section:
"HTML form size should be reduced so it doesn't extend past the textarea"
I will need to see the current form to determine what is being asked here, but restricting the form size should be a trivial matter.
