Removal of water cylinder & radiators

I need draining, disconnection, and disposal of a domestic hot water cylinder and 5-6 radiators. The cold water storage tank in the attic must be kept active and untouched. The house runs on gas central heating, but the system is currently turned off and hasn't been used for a while. One radiator pipe is currently capped off but slightly weeping under pressure, so the system will need a full drain-down. Please let me know your rates and availability.
