My original question was actually how to budget for adwords ad campaign. Thanks
The answer is to budget no more than you can afford and are willing to pay.
Consider your goals and set your expectations accordingly. What return do you need from your advertising campaign? How many clicks will it take to produce a lead or a sale? How much profit do you make on an average lead or sale?
You need to figure out all of these things in order to know how to set your budget to help you achieve success.
