Need to install sound system for a bar..NEED HELP!!

[osioradain]

Hi there. Im opening a bar on a budget here in Croatia and I don't have a clue about sound systems.
The place is about 150m2 divided into 4 rooms main entrance has about 45m2 then a room of 15 then a room of 20 then a larger room of about 45m2(where I hope to have some live music in the evenings)
I will probably have to get a second sound system for the live music, I dont know??? but i need some way of controlling the music from the bar possibly controlling individual rooms(as well as 2 outside terraces) and a way of putting the tv sound through it in case there's a big football match or something.
now im on a bit of a budget maybe €1000 no more than 2000.
Any ideas?
Please keep it simple coz ill have to do all this myself
Thanks.
