Good afternoon, I saw your logo project request and believe I may be able to assist you.
I'm new to freelancer as my profile reflects, however I have been a graphic design freelancer since 2010 when I graduated with my Bachelors degree in graphic design.
In viewing your current logo a few ideas came to my mind using variations of the purple you're currently implementing. A few questions I have are if you're planning to use this logo in any projects requiring it to be smaller then an actual quarter. Also if you would prefer any color other then purple or if you would be interested in multiple colors.
Of course I would be thrilled with any additional thoughts/concerns/ideas. My first round of logos can be ready tonight for your review, with all additional alterations being complete by tomorrow evening or at your earliest convince. Various file types (.pdf, .ai, .tiff, etc) will be provided as well as black and white versions for different printing needs.
