for 70 USD to make a twitch.tv subscription python script that presses "enter" when a subscription occurs

When a subscription occurs on my twitch account I would like my computer to press enter so that another program I have running will actuate a motor. I need someone who is familiar with coding scripts for [login to view URL] subscriptions so that this project can take as little time as possible. This may be challenging for someone not familiar with the repository on twitch. Thanks ahead of time.
