Hello, I am highly experienced in this sort of work and would like to bid on the project, please see my CV. I have done some python but will use Perl since I am most comfortable with it and existing modules make it quite easy. (So I would like to see your perl and python examples though it is not really required). Can use API or scraping as needed, and will ensure low load so as not to alert the site. Can use mechanized form filler to follow submission forms or Next links, etc. Can run from my linux/mysql server and provide you with both source code and a dump from the mysql db easy for you to import into your own database. Also, if you wish the data from the different sites to be integrated into a single database, I can make a data model that will allow differently named/defined data columns from different sites to be automatically integrated. Object oriented, clean, commented code with easy to edit configuration file will be easy for you to modify later. Will provide command line script or if you prefer can be run from a CGI (web) interface. If you want to pay an extra $200 I'll be glad to add a graphic user interface as well.
