I'm fed up with the pizza round here, that's why I make my own but my oven is crap so I want to buy a deck oven and cook some proper pizzas!

I need to able to justify the purchase though and I have always wanted to sell pizza so that's where my idea comes in. I have been thinking about ways to sell pizza whether it be by the slice or whole pizzas, only problem is I have very little capital to work with. So for me mobile catering is even a no go at this point due to funds.
My idea is to run a business from home, straight away eliminating the need for an expensive business premises. I figure I would need to get the place kitted out on a budget and get it all inspected for a health and hygiene certificate, but this should be pretty straight forward and cheap to do.
My niche would be to offer NY pies made with quality ingredients, collection only, and then mass leaflet drop my local area and advertise online. This would simplify the logistics of having to employ and rely on delivery guys. I live in an urbanized area with quite a high population density.
It would be a one man job so overheads would be virtually nothing and profit margins would be high. My salary expectations are also low, I figure I could make £5/pizza and would only need to sell 10 a night to make it work.
Does this sound reasonable, do you think I would get enough business?
