Hi Alistair, after looking at the project files I can see that this can be easily accomplished for you.
To answer your first question, I would use a program called AutoitV3 to write the bot. This will give the bot the capacity to import the text output from Keyword Snatcher and to react when it changes, hence solving the problem of sensing when a search is completed.
As for your last request, I am unable to provide examples of my previous work due to computer failure and the nature of some of my previous automations. Although I am willing to provide details of these if needed though pmb.
Also, because this bot is so simple, I beleive it can be completed for you within the 7 day timeframe. I have selected this as a guidline only.
