RAD studio developer

I was reading online as curiosity and I found this offer and I would like to know for curiosity what you think about if you could do something like that: Looking for one or more freelancers for the development of a couple of new features in a tablet application developed in RAD studio. It's a Windows app for intelligent lighting in hospitals. The basic task is to add a new tab within the app. In the tab there needs to be a list of “scenarios” to choose from. See pdf in link for UI (might take a bit to load). (the tab "Generelt" is already done and not part of the task). [login to view URL] When a scenario is choosen the following 4 things needs to happen: 1 - a specific time-dependend DMX scenario is output (the DMX interface is complete and already in use in other tabs) 2 - a specific videofile is played in the background 3 - a specific audio file is played in the background 4 - a web-browser tab needs to load an ip address and start a wi-fi connected aroma dispenser in the background (the aroma dispenser already has a web API) As shown in the UI a volume slider ("Lydstyrke") needs to be present and control the sound level off the audio-fil or just the tablets audio-out minijack. The radiobutton "Duft-effekt ON/OFF" is supposed to control whether the aroma-dispenser is going to be ON or OFF. As our software is to be continuously expanded, it is highly possible that more tasks will come on a regular basis and, in some periods, may constitute full-time work.
