I have recently quit my job as a developer at Amazon to work as a full time freelancer. I can do this for you in Python, Perl, or PHP, whichever you prefer.
Here are examples of some of the spiders I've created:
1. A spider to check a specified blog url for posts. Extracted all titles with names and dates and comments to an excel file.
2. A spider to query google, Alexa and other pagerank providers for ranks and other info on hundreds of urls. Had a very detailed proxy system.
3. A spider to log into ebay, search for all products that fit a specific description, bid on them, and then output the result to a csv file.
