Money is awesome, period.
And if you want to really let them know how valuable they are, get this dollar amount printed on HUGE checks. You know those huge checks you give people when donating to charities and the like? Do this.
Of course, you can`t cash it; it is a mock up of the real check. But present this in a ceremonial way, and they will feel appreciated- rather than have them feel like they have been gifted in a faceless/dollar amount kind of way. (which is still okay for me) :)
But you can really speak volumes going that extra mile, make `em feel appreciated Like you put some thought in to it.
Interesting topic for someone like me.
I used my name and am experiencing no problems.
Then again, if you have a name like John Smith odds are your site is already taken.
Sometimes, it`s better to spend 11 dollars for a totally unique domain name than it is to buy one that somebody`s hold on to for profit.
However, in the case that Pizza.com becomes available for 300 dollars, you know the common sense thing to do is to buy it.
Perhaps you are charging too much, or you are not getting enough ratings for them to seriously pursue an interest in advertising with you.
If none of the above, you may need to hire a sales forces to contract such offers for you- or do so yourself.
Hope this helps.
