How important is your domain name?

[Paul Bowers]

I'm getting ready to start doing some direct mail marketing and want to set up a lead capture/generation page.  I already have a website for my business that I could modify for this purpose.  Or should I set up separate/additional domains names, i.e. webuyhouses . com etc?  There are some decent domain names available for my area but not sure it's worth maintaining a separate site for each domain.  What are your thoughts?
