Google Analytics integration

We are interested in building a Shopify plugin that integrates with Google Analytics and automatically grants reporting access to a third party (with original user's permission) in order to run a competition. We are looking for a professional developer who can deliver a fully functional product in a relatively quick time period. What the product will need to do: - Preferably, the product will be downloadable from the Shopify app store - Upon installation, it will prompt the user to approve read and analyze access to Google Analytics - That access will be given to a GA account to be provided, and will then be used to judge contestant companies in a contest - The app will also provide a badge for participants to place on their site (badge graphics to be provided) What I am looking for is a project estimate. I need a time scale and an explanation of what you think needs to be done to get this launched. Details matter here, as does collaborating with someone I can trust and build a relationship with. To make sure you've read this far and understand what we are looking for, your message must include the phrase "going back to Cali" to be considered.
