Hi, we've got just what you're looking for!
Our custom MVC framework is an excellent fit for your online store.
We specialize in social networking and have built sites with very similar functionality to what you're looking for. In particular we've worked on a marketplace for a 3d printing business, which includes profiles, product management, extensive filter functionality, and shopping cart with payment integration.
We've got a highly skilled, full circle team that can assist you with all aspects of development, including design, front/back-end, QA, testing, and hosting solutions. We specialize in Python, but have excellent PHP/MySQL developers as well.
We can really hit the ground running with much of what's already constructed on our framework (profiles, products, user levels, admin panel with the ability to manage members, profiles, products, and pages, payment integration and more).
Let's get in touch to go over your specifications together and move forward with the discovery and knowledge transfer phase. At the same time I can arrange a Skype demo of our work and what we can use as a starting point for you on our framework. This way we can get a lot accomplished in a short time.
I look forward to hearing from you.
Alex
