You're not going to like every design that you see. It's important to remember that design is subjective and what one person may love, another person may hate. However, as a professional designer, it is my job to make sure that you are happy with the final product.
For "pay-as-you-go" clients, I offer three revisions. This means that if you don't like the first design, we can work together to make changes until you're happy with the result. For premium clients, I offer unlimited revisions. This means that no matter how many changes you want to make, I will work with you until you're completely satisfied with the design.
