Book cover design

I require someone to design a cover for my book, which is called "Funny English Errors". The cover has 3 parts: front, back, and spine. I will supply the text for the back and spine. But the first task is to design the front. I have in mind quite a simple design for the front, incorporating just a few elements into the typeface. For example, the "u" in "Funny" might look like a big grin or someone laughing; the "o" in "Errors" might be an upside down smiley face (ie, a frown). The typeface for "Funny" might be something jolly and funky; "English" might incorporate the colours of the Union Jack; "Errors" might look like a red ink-stamp. I am open to any other ideas. But it is critical that I will own the copyright in the design and that all fonts are free for commercial use, since the book will be published worldwide. Please provide samples of your previous work. A mock will be welcomed.
