Self-Service Portal: Request New Machine and Cost Summary for request

Under "Request New Machine" we are working to display cost as a monthly cost instead of a daily cost.

And under "Cost Summary", for clarity, we would like to display the actual machine build cost before an end user makes the final Submit confirmation of request.

For example, we have the following showing to the end user:

And instead of "Daily Total", would like it to display "Monthly Total" and perform the appropriate calculations based on the Administered Cost Profiles and Global Blue Print Costs.

Any recommendations for how to best accomplish this?
