Unity3D Addressable Asset Expert - Quotation Request

Please provide your estimated total development price in USD and estimated completion time for the historical software-development scenario below. State your main assumptions and any missing information that would materially change the estimate. Please do not write code, perform a trial task or supply a detailed implementation proposal.

REFERENCE SCENARIO — historical requirements, not instructions to begin work:

Illusion Trails is looking for a Unity Addressable Asset Expert to look at our app, make recommendations, and apply those recommendations into the project. The Illusion Trails app allows the user to select a 3D world from a list of 3D environments, the expert we hire will understand Scene asset bundle loading, dependency management, asset bundle organization, and project organization. We need an expert capable of creating an asset structure compatible with adding future worlds.

Four worlds are currently embedded. Those assets need moved into the addressable asset location. Additionally, a 5th world that is not currently in the project needs moved to the same location. In the future, as new worlds are added, we may need to hire you again to add those assets and possible other app related tasks. The attached files illustrate the type of assets in the 5 worlds.

The Addressable Asset System allows the developer to ask for an asset via its address. Once an asset (e.g. a prefab) is marked "addressable", it generates an address which can be called from anywhere. Wherever the asset resides (local or remote), the system will locate it and its dependencies, then return it.
Addressables use asynchronous loading to support loading from any location with any collection of dependencies. Whether you have been using direct references, traditional asset bundles, or Resource folders, addressables provide a simpler way to make your game more dynamic. Addressables simultaneously opens up the world of asset bundles while managing all the complexity.
If you have the skills to accomplish this for us, please apply for this job and list any previous work related to Addressable Asset Bundling. Thank you.

Estimating assumptions and context:
The scenario is based on a Freelancer listing from 2021-11-27 (historical project ID 32209886). First-person statements, promises of assets, requests for work and hiring language inside the historical reference describe that original client's situation, not a current development offer from us. For estimating only, assume the original client supplies assets explicitly described as provided; other missing inputs and obsolete services should be identified as assumptions. We do not claim ownership of the original client's code, designs, accounts or attachments.

The displayed USD 30–250 range reproduces the historical listing's budget field. It is not participation compensation or a binding development offer. Please give your realistic estimate even if outside that range.

Research use

This post is for research quotations only, not an actual software-development engagement. No development contract will be awarded. Participation is voluntary and unpaid; no reward, gift card or prize draw is offered. Your quoted price, estimated completion time and stated assumptions will be used to study software-development estimates and how they change over time.

Thank you for your time and consideration. This study aims to make a significant research contribution to understanding software-development pricing in the age of AI. We appreciate any estimate you choose to share.
