It sounds like the John Britten/Desmond Norman model of developing an indiginous design, in house, and having ones own manufacturing facility. Great idea, could do with about £20 million for seedcorn, employee costs etc.
Would one be abused if one said perhaps you arer jumping the gun? Little aircraft manufacturers are going belly up as they find the costs of processing their design into fruition, and ironing out the problems exceed the actual costs of development? Get qualified, learn your trade first with others paying you, and take it one step at a time, rather than trying to leapfrog over people ahead, immensely talented and far wealthier (but still not rich enough). Sorry to be rude, but you haven't even learnt anything yet.
