Tool to Automate Form Filling of specific forms

Avg Bid (USD)

$30 - $250

Project Description:
Hi I'd like a tool (a desktop program, not a browser plugin or web based) that I can, having loaded up Firefox with the form, tell which website I want to fill forms at, and then which set of information I want to use, and it will fill the form out. I don't want it to submit the form automatically.
There's about 15 different pages I'd like this to work with, and likely more in the future. Also the forms change occasionally.
However, I am posting this task for just 5 forms to be auto filled.
There are no CAPTCHAs but some are multi-page.
I will go into more detail with the right person.
Experience using AutoIT or iMacros would be ideal I think - though I am not a programmer so perhaps there is another way that would be better.
Please send me a message explaining briefly what technologies you would use to do this and how long you think it might take.
I do not want the website to know that a script is filling in the form.

I've selected Website Testing as a skill that's related, only because I had to select at least one skill.
