Before designing a website and making business cards, you must first buy a domain name. Check out www.godaddy.com and purchase a domain with your name in it.
For instance, www.martinbentsen.com would be one I would buy. If that's not available, try adding the word "actor" next to it. So www.martinbentsenactor.com.
Once you purchase a domain name, (about $15 per year), you'll be ready to proceed to the next step, which is getting your resume looking great.
The next post on that will be up soon!
