Is this something that interests people if we are able to charge reasonable prices?

Reasonable means something different to the seller and the buyer. I cannot imagine a price point you could offer that would make you a 'reasonable' profit and would still look like a 'reasonable' value to me.

This would essentially be a high-end luxury service and most backpackers are not in an income bracket where it makes sense to pay for that amount of convenience. So, although I'd like to be encouraging, I think you are pursuing a chimera.
