For your testimonial we will set up and configure Google Apps (including the commercial version of Gmail) for no charge.
Up to 10 users can be configured (charges will apply for more than 10), with 25GB of storage in each account.
Typically, your accounts are ready for use within one day of providing your domain and MX (mail exchange) record information.
Note that deployment is free, however the standard ongoing charge of $5/month (or $50 a year) will apply after the first 30 days.
