Create the next Logo Design for RazzleberrieZ Yogurt

RazzleberrieZ Yogurt

We are opening a brand new self serve frozen yogurt shop in Phoenix AZ. This is our first store but we want to expand to more within the next few years. We want to make our own brand recognition and be different from our competitors.
Our shop will have flat screens, wi fi, music. Our decor will have some berry images and be in the color scheme of Bright purples, grey, silver and brown (please refer to attachment titled "gray brown and purple" for exact shades). We want the atmosphere to have a very trendy, modern, clean feel to it.

Our location is in a high traffic shopping area.
We want to appeal to all ages. Our customers will include kids coming in after school to hang out, coaches bringing in their teams, families, mothers, teenagers.

We will have a Facebook following, and promote community events and service.

The name Razzleberriez Yogurt must be incorporated in logo.
(another option could be to use RbZ for shorter version)
We would like to see at least one berry in the design – prefer Raspberry.

Our Logo should represent our name RazzleberrieZ Yogurt well.

Some sparkle or stars that make it look like the words are sparkling might be a way to bring out the "razzle" part of our brand name. ( just an idea).

The logo should be a modern, creative and trendy looking. This logo will become our brand recognition for all stores.

Logo should be in color scheme of Bright purples, grey, silver, and possibly brown. Our store will have these colors incorporated in the interiors.

We will need all copyrights on logo.

Logo should be one that we can use for print on print media, T-shirts, packaging, website, signage etc…We will need the following files:
Print file format; web file format, vector image (no background), etc.
EPS file.

Please, no clip art designs.
