We're launching for Android on new year's day! (http://fitsby.com if anyone's interested)
It will work just like your regular debit card works when you are in a foreign country, the conversion will happen in 'real time'.
SalesForce Themes and Skins
Never dug into the law (here in Australia) but I want to make available the tool for people the manage their own properties, some standard rental contracts etc.
People already look for property online, then you have to deal with the agents, you should just be able to deal with the one - hopefully trusted - site. You search, find, go to a open inspection, apply online, get notified that you have it. Get sent contracts etc. Organise a meet for keys and signing. You'll then manage communication through that with the owner or a proxy.
You'd need to hire a bunch of resources that are vented to do open inspections and manage some calls etc. but on scale they'd be cheaper than a bunch on real estate agents.
You don't need to hire them - just subcontract with them. Kinda like what Home Depot does for installation work - they have a vetted network of contractors around the country that they schedule...
Good luck
