With this logo, I used a visual double entendre of a barefoot/footprint made up of water droplets. This image is simple, approachable and memorable. I feel that it can stand alone without text and still convey the essence and personality of your company. Paired with unique typography that almost mimics the flow of water, this logo positions your brand as professional, experienced and friendly. Customer service is key in your business and I feel that this logo perfectly communicates your commitment but still reflects a fun personality. I like to think of a logo as brand's fingerprint.
The barefoot icon I designed is simple and clean so that it can be scaled down very small for business cards to large for vehicle signage. By keeping this simple, you should have no problem embroidering this on employee polo shirts.
I'd be happy to work with you if you require any changes or would like to see more options.
