The plans do not include custom changes. Initially you have to choose from our existing themes or templates.
However, we give flexibility of changing colour combinations, fonts and back-ground images. Moreover, you can take a header of one theme and footer of another, home page of one theme and product page of another.
You also have access to the HTML/CSS code. So this much customisation can be done free of cost. However, any other custom change will have to be evaluated and can be done at an extra cost if it doesn't fall within the scope of your plan.
