OpenCart Graphics and Module Enhancements

I have an OpenCart project that requires a proficient freelancer with both technical skills and aesthetics. In the core graphics department, I already have a logo and other relevant designs; what I need is someone to test and implement these within my OpenCart site.

The following specific modules and features need to be implemented in OpenCart:

-Payment gateway integration
-Product filtering and sorting

Additionally, I require implementation and setup of a product configurator. The configurator should display options and attributes in a manner that is user-friendly and interactive.

Ideal Skills and Experience required for the job:

-Proficiency in OpenCart
-Experience in graphics implementation within an eCommerce environment
-Experience in Module implementation and customization
-Technical know-how of creating and implementing a product configurator

Thank you for considering my project. Looking forward to achieving success together.
