To answer this question, a use case needs to be established which will help you in making all the decisions. First, you have to establish a goal of what you are hoping to accomplish or the project return on investment. Then determine what information you want to play on the televisions today, a year from now, two years from now. Once you have this hashed out, you will know if it is something you can do or if you need to hire someone. DS is a good platform for the money that can meet the demands of most use cases however you have to understand its capabilities and limitations. A Raspberry Pi is a low cost device however the use case for it will be very limited. Do you need a private onsite server or will a cloud server work? How critical is the information being displayed? It's not a matter of if you will have a problem but when so you will need a system/network manager to keep it going (or you can take the time and do it yourself). I have been using the DS platform for almost 10 years and we have been able to make it work for us.
