I have read the details and have done similar work. I have built 10 crawlers in the last 3 months, and many more over the years. If it's crawlable, I'll crawl it. It's odd, but I literally love data.
Relevant Skills and Experience
MySQL, MariaDB, PHP, JS, JSON/XML/HTML Parsing, JS/PHP Parsing, Python, server management (as well as dedicated IP routing for anonymity with crawler), fake user-agents & header info, and more.
Proposed Milestones
$295 USD - Initial crawler
$295 USD - Finalized crawler
$71 USD - "Clean data" (fixing up data to be properly formatted if crawl sources have different formats)
