Start-up Frozen Yogurt Shop needs Logo Design

Chilly Billy's

Chilly Billy's is a small start-up self-serve frozen yogurt store. It is a fun, bubbly place with healthy, fresh yogurt & toppings. Customers will serve their own yogurt in a cup and add their own toppings (ranging from fruit to candy, etc). The look & feel of the store is modern, bright, and vibrant.
The logo will be used for signage, website, uniforms, advertising, etc.

We expect more female than male customers but we don't want the logo to be feminine.

We are fairly wide-open, but we know we do not want the logo to include characters like animals or cartoons.
We want the logo to say Chilly Billy's Frozen Yogurt
We haven't selected colors for the store yet but we anticipate that we will use a dark pink and orange. We are looking for a 3rd color, or we are open to completely changing colors if there are other ideas.
We want it to be bright, and not too formal.
