How long will it take to run initially to rebuild the database to the point where your aws instance can take over?
If it's only about 12-240 hours I can run it on my normal computer, if not, I'll purchase a vps from somewhere.
For the amount of time it would take me to reprogram the tool, I would want you to run it all the time.

It would take both of us 11-12 days.
Look into Amazon - they offer a free VPS with many OS for free - you just pay for usage over the free amount.
With my parsing tool running 24/7 it cost me about $3 last month.
OK, I got a code from theymos to bypass the captcha for an alt.
I'll take a look into that Amazon one, is it ec2 you were using and is there a way to track your usage as you go, so I don't get extensive bills at the end of the 12 days?
