Twitter Research (API access needed I guess)

I have a list of 10 accounts You need to find all the followers (who follows at least one of them) Find out whome the follow and note HOW MANY of the ten follow each of these Also find out how many followers they have Example: I give you ten accounts: A B C .. J They all come from the same industry A has 1.000 followers (put them to a list) B has 500 follower (put them to a list) .. J has 5.000 follower (put them to a list) On that list of followers: Note WHOM they follow, so I can count HOW MANY of the ten sources they do follow. Collect the info whom else these "followers of the ten" follow and count HOW MANY of the ten follow each of these targets, and how many TOTAL followers they have. Also please list for each of them the country where they are located (is that possibled? We are interested only in German accounts) Result is a list of important twitter accounts in the industry from which the 10 sources come Optional: Please advise whether it is possihble to also get the normal web address (these are all businesses) added to the list. The sources are: @print_de @4cmagazin @VDMNW @flyeralarm @drucktipps @Heideldruck @printshopblogge @VDBNET @KBA_news @manroland_web
