Diablo 2 Resurrected Packet Library

I am looking for an experienced developer who understands Diablo II: Resurrected (D2R) packet structures and can create a working packet library for specific in-game actions. I need the following functionality implemented and working: * Teleport using the appropriate skill/action packets * Pick up a dropped item using its specific item ID * Open/interact with chests * Leave the current game An important requirement is that these packets must be actually tested and verified in-game. I am not looking for packet documentation or theoretical implementations that have not been confirmed to work. I would also like a very simple UX/test application that allows each action to be triggered manually so the functionality can be demonstrated with a character capable of performing the actions. For example: Teleport Pick Up Item [Item ID] Open Chest Leave Game The deliverables should include the complete source code for both the packet library and the test application, along with any supporting packet structures, serialization/parsing code, and basic documentation needed to integrate the library into another project. The packet library should be reusable independently from the test application. Experience with D2R packet structures, networking, or similar D2R development is strongly preferred. Please mention any relevant previous work in your proposal. ** Note: This is for online play and needs to function online.
