Add colliders to existing maps in Unity Editor

Due to a Guru Meditation error we are in desperate need of immediate assistance with our colliders in Unity for the setup of our maps within our game and would like anyone with the relevant Unity skills to help out. The task at hand is to add sets of Unity Box Colliders to a series of 8 small maps within a 2.5d environment and add the following requirements: * 1 set of Base Colliders for the bases of objects * 1 set of Background colliders that trigger the z-index shuffle to allow a player to go behind the object A map may also contain a series of overlay items that must have both colliders attached to new Sprite Rendered for items that are not part of the base overlay or are crossover items that require a different collision. This is fully explained in the document provided (and an example and ready rolled prefab is available in the package too). A Unity import package will be provided with the complete list of files in the correct structure and an explainer document on how to complete the task to the level of detail we require it. I have attached an example too to show what a completed set for a map looks like in Unity - we expect a high degree of accuracy in these colliders so an eye to detail is a must. The freelancer will provide back the completed solution as a unity import package also for review and testing before completion and sign-off. This task requires immediate attention so it suits someone who is actually doing the tasks, not a third party "studio" sat above the actual developer. I expect the results back quickly and diligently, and am available for immediate feedback and testing.
