Steam software

Programmer services are required. You need to write a program for the application with Steam games. I just have to log in every day and get a reward, but the problem is, you have to do it for 1,000 accounts. It takes a lot of time if you do it manually. Can you write a program that just enter logins and passwords from accounts and make it just go into the game skip the initial video and then leave the game (nowhere to click the reward will be automatically received when you log in.) Then the program goes to the next account and similar actions. How much does it cost and is it possible to do so, given what I have said above?
