Finding a home in Northumberland for our new stati

Hi

I have just bought a cheap static to allow my kids to get away at weekends and explore northumberland, i am looking for a park to site it.  As it's our first van i need somewhere cheap and flexible (doesn't need over the top amenitys, just the basics),Has anyone any suggestions and a guide as to how much i will be looking to pay to get a static put onto a site and hooked up etc

Many thanks
