​Creating a website for a small consultancy work…

Hi all,

I’m incorporated, but I would like to build a website to showcase to clients. However, I picked a very random/generic name for my corporation registry. That said, can I just pick any website name available (presuming I don’t infringe on any trademarks etc as I don’t plan to do any large volume of sales) when presenting to clients?

How about when I bill or write contracts with clients. Which company name should I be using?
