If I decide to save and buy the PA. How much does such a system cost? An estimate?
How high is up? Depends on quality, features, brands and discounts. A small PA, probably R10K - 20K, a midsize one about R50K - R150K and the sky is the limit on big systems. That's why bands usually own the PA together, grow it slowly over time and regard it very much as a business investment.
The last PA system I owned I bought piece by piece and it took about six months before I had a complete system. From there you grow it, adding on and upgrading speakers and amps, crossovers, monitors, etc.
