Instagram checker

I want to develop a program related to instagram using java, python, or any other programing language suitable for PC. This program function is to make a txt list of usernames, like: abc Abv Abn Abj Abu Or even adding the single username required, and then I create a temporary username for my account on instagram, e.g. "Abc334455". After that, I log in the program using this username, with determining the program speed, and the run the program. The program starts scanning the list made or the single username required. When there is a username available of the list, the program automatically exchanges the temporary username "Abc334455" with the required available one, e.g. "abj". Important notes: 1- The program scanning speed must be highly great, because there is great competition with otherprograms regarding this point. 2- The program must not get a sudden break or be banned; instead, it must work continuously, strongly, and speedily. 3- This is the program concept, but there is still a space for creating another concept performing the same function, using proxies or without. Please, do not apply for doing this task until you are sure that you understand what is required and you can do it, in the professional required way. This is a simple program, but it is concept is the most important. Moreover, it may require future connection updates with instagram, if required. Waiting for your creative offers
