VM provisioning on VMware

Hi Team,

We are using ManageIQ to launch VMs on VMware but the cost estimate for the VM has to be presented before ordering in the Service Catalog itself. How do we do that?

There are couple of companies having their own VCenters and they want a single catalog for provisioning VMs, where they can select their company, datacenter, network and get approval from their respective managers. So we need to select multiple tenants within a single service catalog. How can we achieve it ?
Can somebody help me out.
Thanks in advanceā€¦!
