Currency & Language options

Currency & Language options

Various questions for you:
We are a UK company and have a Brazilian subsidiary who want to have the option to use our Zoho crm in the Portuguese language with a dollar currency option.  We currently have 2 licences for the Professional Plan.  We were thinking we can use 1 licence for UK and 1 licence for Brazil but would need to upgrade to the Enterprise option to include multiple currencies and the ability to prepare quotes etc in dollars and still be able to have Sterling as the home currency for preparing our own quotes.

Can we operate with two languages and if so what is the most effective way to operate this?  What screens will be seen in which language? Can both licences be linked but in different languages/currencies? Can the UK licence holder see both the UK & Brazilian contacts and the Brazilians just see their own contacts etc in Portuguese?

Really I'm looking at the best way we can set up and run the crm to meet our operational requirements.  I would be grateful for any advice you can offer.
