WANTED - rustic Sicilian food for our wedding reception in casa rurale?

Hi there my fiance and I decided against a reception in a hotel, for our wedding in Sicly, for various reasons one of which was cost but another was a healthy suspicion that such an arrangement in a bog standard European hotel might leave our guests feeling unsure whether they had visited Sicily at all.So we decided that after the Church we'd invite them back to our humble casa rurale, pitch a tent, crack a bottle of prosecco and go from there.  The idea is to let people be amongst the olive trees, cattle bells clanking, rub shoulders with the neighbours on their home patch, feed them rustic food like a lamb on the spit and generally return them home happy and well fed feeling like they got 'something out of' their trip away.Initial contacts with local catering firms suggest half are booked already and the others just don't 'get' what we're trying to achieve.Has anyone tried this sort of rustic catering themselves or had experience of such an occasion?  How was it achieved?If we find a roasting spit large enough for a sheep thats part of the battle won (Google.it searches throw up small spits suitable for chickens but little else) - but where to find a catering company that can pull off the rest in a laid back, family style?Any thoughts on topic would be great...RegardsLiam
