Converting Single User Account to Multiple Users

Hello,

Our company has grown, and with that growth we need to add more users to our account. Until this point we've used one login for multiple users, and scheduled all meetings inside the single account.  When we started with two concurrent meetings we added more users to our account. We now find ourselves needing more than two meetings at one time, and we need to upgrade, but we can't make head nor tail of the instructions, and we are overwhelmed with options. Does anyone know of a consulting service who would come in and get us set up for a fee? 

Thank you
