If I may I'd like to pick your brains by way of market research 
We have a small campsite with just 6 pitches. No elec etc but beautiful if I do say so myself.
I'm thinking of putting a pizza oven on site. Customer would need to light their own fire and cook their own pizza, but we would/could deliver the raw ingredients to make the pizzas.
What do you think? A good idea or just fluff?
TIA
