Design E-Commerce Site With Payment Integration

I’m setting up an online store and need a designer-developer who can take the project from concept to launch. The site must be fully responsive, branded to match my guidelines, and—most importantly—come with a rock-solid payment gateway already wired in, tested, and ready for customers on day one...
