coffee machine advice please

[DT Vending]

I have a site (Horse riding center) That have asked me a few times for a coffee machine. This is the situation !! There is no water on the site but power is available ! They have said that they can take a fresh container of water to the machine each day. Are there any machines that would be suitable to work this way ? and also with minimal assistance required as the site is not local to me so don't fancy a 2 hour trip for a call out every few days !!! I have zero experience operating coffee machines so any help much appreciated.

You can get a jug fill machine, I would look at an in cup machine like a Darenth. Loads on ebay with coin mechs. However I too have a busy riding school/yard but it does no mre that £30 a month so hardly worth it to be fair
