help building the website

I'm looking for help building an e-commerce website also with an informational purpose. I'm seeking a moderate amount of customization including some unique features, but I'm open to platform suggestions. I'm excited to see what creative ideas you might be able to bring to the project and look forward to hearing what you have to offer! basically it is a website where you can buy shirts etc and some of the funds will be used to do kind things for people.
