travelling companions

I am planning to go to Italy, 2 destination s - Tuscany and Liguria - and wondered if there is anyone out there who is also planning a trip and would like to share costs (of travel and accommodation).    I am going to look at the areas and also properties for sale within those areas.     Any guidance would be very welcome, i.e. renting for a few weeks etc.    Sept./Oct. would be good - perhaps not so many tourists.     Thanks.
