VMWare Server configuration an VM access

Hello, We have a vSphere Server on which we would like to create virtual machines and connect to them with. These VM are for students that will use assistive software. We have an idea of what we need as a configuration but know not really much about VMWare. We need a consultant to help us make the following possible (if possible): - We want people to be able to loan a VM from a web interface (at the end of our project) --> web app that would trigger the creation of the VM by command line probably. - We would like the licences to be attributed dynamically when the use is needed. Each software we use have a serial number. - We would like the best VM configuration for the best operating of installed software. Thank you very much. Michael
