Implement Mouse & Keyboard Input System for Virtual Tabletop Card Game

I'm looking for a Unity developer to take on this freelance job. The deliverable is essentially a Unity project which implements the input system of a virtual tabletop environment for a tabletop card game. The input system would be designed for mouse and keyboard input and be event-driven. It would require implementation of: Single-selection of a card / object via click Multi-selection via key modifier + click [ex Shift + Click] [keys not hard-coded] Multi-selection via rectangular area selection box [drag mouse to select area, select all intersecting cards] Double-click event triggering [without interfering with single-click event trigger] Context-menu triggering [ex Right Click] Drag and drop of cards [without interfering with single-click event trigger] Ability to drag cards to and from UI [Canvas] elements Ability to do all of the above, without interfering with UI [Canvas] elements Gameplay is outside the scope of this project. The UI (other than ability to drag and drop to and from the UI) is outside the scope of this project. This project would serve as the basic framework upon which the gameplay and UI would be built. So I would like this project to have the behaviors and interfaces necessary to build upon. This is not a time-sensitive job. Completion time is open for discussion. I am willing to hear proposals for a different / better implementation.
