I'm reading a really great marketing book at the moment called 'Your marketing sucks' by Mark Stevens.

In it he makes a point that you could spend $1Million on marketing, but if your message is not clear, and not being  told to the right people, you will make NO SALES.

Be creative, but make sure IT WORKS.

if it doesn't make a sale, don't spend any amount on it.

I strongly recommend this book and others in the category to give you at least a basic understanding of marketing and how to effectively use it!
