Custom Template for Big Commerce Store

We have a bigcommerce store setup that we are going to be launching. The store hasn't launched yet but will be soon. We require a custom theme/template for our website which will require you to incorporate our logo into the theme etc. This is a toy and hobby website that sells retail kid toys and mid age hobbies robotics etc. When submitting your quote please give a general idea of colors etc that would be used with my logo attached to create the template. You must have bigcommerce theme experience. Please also submit a few examples of templates you have done in the past.
