I don't mean to be harsh or anything but.......
Asking to spend 6 months at someones if you can't find a job is never going to happen, just to rent a bedroom in a 4 bed house costs me £325 a month, so your essentially asking someone you don't know to move in AND FEED YOU, when if it was a lodger who did the same thing then you could make about £2-3k (I mean if anyone wants to give me space and food for 6 months I'm probably willing to move! haha). I'm not trying to knock your hopes or anything; if you said you were planning on coming over for 2 weeks then I'm sure people would have been a lot more inviting.
And I don't think asking on a public forum, "if someone had a small grocery or something, it could be possible." is a great idea. In fact I'll leave no further comment on it, it's not a great first impression though.
IMO you need find out your legal requirements for working over here, if you own a Ducatti and a car then you must have some sort of skills that may be useful to us. I thought that under the EU you could work here legally, so start applying to places and ask on here for any advice with certain areas that you are interested in living.
