Costs or Quotes for requests / ITIL - Financial Management f

My department primarily provides IT Support to our company and so I am happy using Service Desk Plus. However we are often asked to provide reports or develop intefaces for our company's clients. These requests always come in through the service desk but quickly require us to provide a quote / costs back to the requestor. Ideally I'd like some integration with CRM products or a built in workflow to enable us to have a quote/cost approval process.

I believe that if you wish to implement ITIL into the service Desk, in this case "Financial Management for IT Services", then this may be something to consider.
