Can anyone reccomend me a campsite in Dorset/Devon?

Hello, im looking for a campsite near a sandy beach anywhere in Dorset or Devon ( not too far into devon ) and i want a campsite that is very small and simple just literally a field thats cheap! :):) I find its much nicer camping in simple places and if anyone could reccomend me somewhere like that that would be brilliant or even if someone could reccomend a good beach .Thanks :)
