Wow, very nice. #4 looks great. Office suggestion, because we are a part of Nationwide. Keep everything the same, just add a rectangle (tall) around the letters of the logo. Make letters of the logo white and placed on the baseline. Keep the name text the same.
Here ya go. I hope that i got your feedback in correct order. If not... try -try again! if you have any other suggestions please do not hesitate to write or even pm. Thanks again for the ranking
