Hello there,
I'm a UK system engineer and technical architect and offer large-scale UMLmodelling services, usually on corporate R&D projects- working on-site.
On suitable projects, I've also been known to pffer UML services on here, and may be able to help you.
Let me know when you need this, and also, if you would be OK, with me using MS VIsio for drawing the UML diagrams?
