Developer Needed for BigCommerce Stencil Theme Customizations

We are looking for front-end developer who has experience working with Bigcommerce stencil themes. There are a number of customizations we would like to implement over time.
Currently, we would like to redesign the header and home page. Mockup and responsive html/css code will be provided by our designer.
Please provide the following information with your cover letter:
- relevant BigCommerce experience
- why you will be a good fit?
- preferred payment terms (fixed rate per project vs hourly)
- desired hourly rate

Quick turnaround and responsiveness are very important to us.
Thank you
