Shopify Theme Editor

I have an existing website and we are looking to modify the layout of the home page as well as make some small adjustments to the some of the internal product detail pages. Here's the deal, I will get tons of responses from a lot of freelancers who have no business replying to this ad. The most important thing that will effect my decision with who I go with are those who meet the following criteria: 1) Prove you have past experience in working with a live Shopify account. 2) Explain your process in detail to ensure you will work in a sandbox account to test the changes before launching to the live site. 3) Preference to those that also have experience with customizing Wordpress sites (especially with ACF - Advanced Custom Fields). If you have experience with this, please include in your reply. 4) You read and follow instructions. This is important. I will immediately reject all applicants who do not include proof that they read this entire post. 5) You can prove you read the entire job description by including "POA" somewhere in your subject line. POA = "Proof of Attn" Thank you.
