Great branding is about execution as much as presentation.
If you want your brand to excel, then your imprint as an actual service provider needs to be extremely effective and positive for the customer.
This requires the service provider (you) providing benevolent honesty to your customer about your intentions and plans, dedicated communication throughout the development of the project or delivery of service/product, follow through on your goals and deadlines, and follow up upon delivery of service/product.
Everything you do as a company speaks to what your brand is. If you want to be a brand that people can count on, then be a brand that is doing everything it can to fulfill service.
