Since you have a group, and I would highly recommend you take a look at R server and shiny server.
(1) Shiny server
You can totally install Shiny server on a old computer and I would recommend using Linux OS like (Ubuntu) and it will save you some time following the tutorial.

Is a free platform that you can host your shiny app, it is in alpha version and I don't think there is much authentication or security built in. HEREenter link description here is an example hosted on shinyapps.io
(4) AWS free tier
If you have never used AWS before, you can have a micro instance running on AWS free for one year! I would highly recommend using AWS instead F* around with a old computer.
