Custom Bot to Extract Domain from Text File Based on Keywords

***NOTE: READ THE INFO BELOW *** Serious bidders only. I do not care what you have done in the past - tell me how you are going to do this so that I can be sure you are the right person. I have several text files with more than 100 million domain names. It's a text file with one domain per line. I need a desktop bot that will allow me to extract domains from the files based on keywords. There are multiple files based on domain type. The ideal bot would allow me to type all of the keywords I am looking for into a program or external text file and then point the bot to the file and extract the results that match. Searching one file at a time will be OK as I can type the keywords into a text file and save it on my computer and copy and paste it into the program.. The largest text file is 1GB. Attached is a sample file. This will be a simple program for someone so if you quickly create a sample program, I will text it and award quickly. Thanks.
