Live Stream Alerts and Screens

Hi there, my name is Theglacierr-- [login to view URL] and I am a youtuber/livestreamer, I am looking to completely transform my Livestream by adding in unique donation/sponsor alert images and sounds as well as custom screens, and screens that I could use for my green screen. Overall I have a ton of ideas and I am really looking for someone to work with long term instead of just one small project. Preferably looking for somebody with experience and knowledge in this general field. Not willing to pay obscene prices for something that is going to be very simple, but if you do a good job I have a lot of contacts in the industry and would happily provide your name to everyone that I know.
