I need software that will crawl a list of 200+ websites.

Find specific listings that contain keywords "equipment," "supplies" and other variations.

After finding these listings - grab data about the listing including 1) Date 2)Images 3) Description 4) Physical Address.

Then, relist this information on another website.

The site that will re-list the data is a listing website with these existing data fields.

How much should I expect to pay for something like this to be built and what skillsets would someone capable of this need to have?

Thanks in advance.
