Genuine pay sites

I was wondering if anybody knew of any legit sites which enable you to make money online either by surveys on PTC, i'm not sure of how they work exactly or how much money you can make, or when you get payed etc etc, so if somebody could let me know it would be most appreciated.

I.E, is it POSSIBLE for me to make £5.00 from 20:00 - 24:00 by doing whateva necasary and then having the money on my paypal acc?

 

There are a few. But 4 hours = no no, maybe 5-6.
