Dance showss for underprivileged people

I am an NGO from Romania, which organizes competitions and shows in our geographical area. We started doing this from 2013, at our first event we had 70 participants, following which the number will increase to over 3000 participants after years.
What we do exactly:
- we organize dance performances and music for needy children from Timis county
- we organize free dance competitions for children in need and not only
- we organize dance and music camps for children.
Who we are exactly:
ACS ROK ART is the name of the association, and since 2013 it has been a member of the international specialized forums. You can find our activity on our website www.rokart.org
I have participated in various artistic cultural events all over the world, Serbia, Hungary, Russia, Poland etc.
What we want:
- A very important impediment we have in organizing these events is that the highest cost we have when organizing these shows and competitions is with the rental of the sound system.
- In short, we want to buy a sound system with which we can organize music and dance events anywhere, in any space without being limited by anything.
What we want to buy:
- A sound system from HK AUDIO LINE-ARRAY
