static IP. Instead get a regular data SIM eg from Giffgaff For your IPrequirements rent a virtual machine (5 USD / month from Digital Ocean or considerably cheaper < 10 GBP per year if you don't mind taking more of risk with reliability: check out lowendbox.com).
Good solution, another option for Virtual Machines only a budget would be Bytemarks' BigV @ £10/month.
Couple of the guys from Bytemark will be at UKNOF27. Chris
