We are looking to have a web app built that replicates and automates the processes demonstrated in this video. - [login to view URL]
The end goal product would be a simple user interface that automates this task for the user and then presents them with an export of the final list of keywords reducing the time it takes to do this process manually.
It looks like this could utilize this API - [login to view URL]
If possible having this built in PHP would be best as it will end up on PHP based hosting package.
