migrate from avada to divi

I need an existing website rebuilt. I need you to build it. At moment I have the following: - post layout (same category as the online one) - Breed layout - Interview layout (it will be really similar to breed layout) - home page Tasks that I need to accomplish: - to import post contents and give them a correct layout (which I already created) - to handle the custom post types  — Courses — Razze (breeds) — Interviews — Services (this CPT will go under woocommerce as vendors (the site will turn into a multi vendor market place) on avada and import them inside divi  Some custom post types have "relations" between them that I don't want to loose such as: Each breed (razza) has a size and a group, plus an interview (not always) Users who have that breed Some services sell one (or more) breeds An example is simple probably; custom post type interview [login to view URL]  it shows you: - size - group - vendor who did the interview - other dogs who belong to the same group - users who have the same breed Which I don’t want to loose In case you don’t have the interview we still have the breed page with all remaining informations  ([login to view URL]  )  I don't want to loose relation between items and to show them on the right shoulder (as in the wireframe example) on avada I already have them so I believe it should not be hard to have it but I believe the best way is to setup on divi a layout for each category so that all contents that belong to that will look the same
