Please advise. Repeatedly producing high quality fired pottery question. Possible?

I can't afford a kiln and its electricity/gas costs nor do I have room for it, plus I don't have a garden either that's suitable for building a brick-based kiln, nor could I get fuel for it. I can't afford a wheel, I don't have the free space to use one. I don't have storage/drying room or even any shelving or the space for any. 

I do have the capacity to buy clay-working tools (wood/rubber ribs, trimming tools etc) and clay (in small quantities). 

How can I produce, store and fire clay pots, vases, mugs, bowls, dishes, plates etc on a low budget without overly compromising build, finish and firing quality? 

I ask because going to evening classes to produce clay works would be pretty slow and expensive esp' as time would be against me. 

If you know how I could get repeatable and consistently high quality results on a (temporary, I hope) low budget, please advise - thank you. :) 

Just so you know, I live in the UK and could always pay for better equipment if and when/if I can make enough finished items.
