Work for a fairly small Wellington startup with 20 people in our HQ and another 20 or so overseas. 

We use Skype for Business extensively to talk to the overseas team, but now want to focus on our Wellington office and looking at ditching our Spark landline and the couple of cordless DECT phones lying around. Although we only get <5 calls a day, we do get calls for the Finance\Sales team and the odd customer support call. Our US and UK customer support people use Ringcentral to take support calls, but they dont seem to have NZ or Australian functionality. 

So am trying to find someone that can consult or advise the best solution for us but not charge crazy Enterprise prices. We don't need an incredibly complex or expensive system. 

Requirements:

1. Want to give Wellington staff the ability to to dial out to global landlines via Skype for Business

2. Want to let customers etc dial in to a local Wellington number, get a "press 1 for sales, 2 for finance" type message and then be routed to whoever is online at their desk. Would also be great if we could tie an Australian local number to this facility too for our Ozzie clients. 

3. Also considering a door message system, we dont have a receptionist so considering something like this: https://thereceptionist.com/pricing/

4. Sadly seems we need fax capability still too for regulatory purposes. 

Is this something someone can help us achieve for <$5-10K? Or are we looking at more then that for the functionality we want? Microsoft pointed us to Intergen, but seems they had no expertise to offer in this area. 

We're a smart bunch of developers and engineers so keen to get something cloud based
