I'm sure your plan seemed like a good idea at the time but unfortunately it is overly complicated, unworkable, and the figures don't stack up.
Why don't you save yourself a lot of hassle and grief by just going out and buying a share in something to do your hour building ?
£2-3K will get you something half decent near to where you live.
As an example you can get a well maintained IFR PA28 at White Waltham for £2k. £60ph wet and a fixed cost of £60pm, on line booking, excellent availabillity including taking it away for a week if you want. Do your IMC and night training on it while your at it.
When you've done your hour building sell it for £2200 and spend the
profit on beer
(because you will be fed up with hours building by then)

PS I do realise that you may like the idea of owning and running an aircraft but that is a VERY expensive way of hours building.
