URL extraction

I need a script to extract links from a pinterest board such as [login to view URL] . The tool will allow me to perform keyword searches. The tool should extract into an Excel ready or a text file the URL of pages such as [login to view URL] or [login to view URL] and should not be limited to the first 25 - 30 initial URLs located on the page (before ajax reloads the next 25 records). Once URLs are extracted, a second script (or the same one) will allow me to input the Excel or text file and will extract the URLs inside each board. For example, from the above URL [login to view URL] the second part of the script will extract and save in another Excel or text file, URLs such as [login to view URL] and [login to view URL] and [login to view URL] It should not be limited to the first 25-30 initial URLs either. Max budget $45. I'm looking for someone that can start right away and get the job done in a few hours. It doesn't have to look pretty but needs to work.
