Based on the information supplied I would estimate ....... some money
which cylinders are decent quality for the size of the radiators to be supplied
In case you're wondering @Waj Khan, the reason for the 'less than serious' answers is ..... it's an impossible to answer question. and it's one that's been asked a lot of times. We have no idea of location, how much stuff will be needed, sizes, shapes, materials etc - therefore there's no way of even suggesting a ball park figure. Need to see a job to get the required info, so it would be pointless guessing.
