I signed up with Nextiva VoIP service today with the best customer service.  They provided me with a full service of phone, text, mailbox, routing, and video / audio links i can send to my customers that don't require them to download any software. Their web app gives me full access to change anything and they trained me as another CSR was setting up my account.  All in with taxes and fees it came to about $43 a month.  They waived the $100 setup fee at my request and gave me a free month to try out the service.  

What have been your experiences getting this done and what did you pay?
