It's been a few years, but I have had experience using what was then Grease Monkey to automate some aspects of the companies web admin site for use by the technical support team of the company I worked for.
I am confident I can help, though the extent will depend on the website's design and what can be worked out around PDF output (off the top of my head I am thinking Chrome's Print to PDF might work, but I would need to check the extent to which this could be automated)
Being new (I registered a couple of years back to look at the site, but haven't logged in since until today) I will work extra hard to ensure client satifaction, but regretfully I can not make my bid within your proposed budget range. I am confident I can do a better job than average programmers would on this task, and I suspect that may be worth the extra money to you.
Thanks,
Nat
