2501 Help!!-Want to buy an apartment in Florence

Hello there,
My husband and I are looking to buy a studio apartment in Florence or within a 5 mile radius. We need something that is under 200,000 euros and that we can rent out to family, friends, and American travelers. We will be in Florence from March 14-21, can anyone recommend an English speaking agency that will set up a viewing schedule and walk us through all the various negotiations and processes?
We have found many listings on [url]www.casa.it[/url] but of course every listings is with a different agency, we want to know if there is one agent that can contact other agencies and view their listings as well as provide their own listings.
We have contacted some English speaking and UK based companies who said that they will contact agents and find properties for us to view while we are there, but it has been 2 weeks now and no one has gotten back to us yet!
Any suggestions would be much appreciated! Please email me or post to this message, thanks:)

Thanks,
Heather,
New York City
