Migration to Codeigniter 3 from 2

We are based in California and are looking for a developer to help us to migrate to Codeigniter 3 from 2 along these 21 Steps .. . https://www.codeigniter.com/user_guide/installation/upgrade_300.html

We are looking for someone experienced, based in North America to go through our CI2 application and update it to the CI3 requirements, then to upgrade us to 3. For example all our classes would need to be renamed to begin with a capital letter. We have 2 applications (admin, user) each with about 40 controllers and 40 models. 

We also would like to review our security and see how we can strengthen the code utilizing CI 3 features.

Please only contact us if you have solid EXPERIENCE with CI, and can provide evidence of that.
