Adding Custome Feature

Requirements: - You must be heavily experienced with Codeigniter, and have coded using their framework before. - Need to integrate Stripe as a payment option to my website that is built with Codeigniter that currently uses Authorize.net. I also have an admin backend so it should be an easy toggle switch to have both features [login to view URL] and Stripe as a payment processor. If task is completed correctly, and with ease I'll be using you more often and possibly as a primary developer for my website.
