Nowhere does this ring any truer than when hiring a freelance graphic designer, copywriter, or photographer. Here is how I like to explain it:

If you want it cheap - hire the inexperienced. A newbie freelancer may have adequate skills but  can be slow. They have no experience in what it takes to sell the product or service. You’ll have very pretty advertising but without the desired results.

If you want it fast - even an experienced, knowledgeable freelancer can make costly mistakes. This is what happens when anything is done in a hurry.

If you want it  good - a trusted freelance professional will be given time to do the work correctly. Your advertising will produce successful results and your company will profit from the investment.

Advertising is like most things in life… you get exactly what you pay for.
