Know that if you ever have the desire or need to re-brand and/or re-position, you will face many challenges. Sounds logical after the fact, but as you go down that path of associating your name with the brand, it is easy to let the ego, or the simplicity of finding the domain name, run the branding process and push you into the limelight for good (may that actually be for better or worse!). I would advise against it so you can grow your business, eventually. Your personal brand will always be in the foreground and grow, regardless.
