Welcome Tim. Thanks for logging in. Good to have you on board.
My understanding is a garage approach ramp that goes up 48" will require 48ft of 36" wide ramp + adequate landing spaces for the switchbacks. I suspect it will dominate the garage. (Is this a single or 2 car garage?) If the laundry room doorways are 30", this may be the more difficult plan. It may be faster to do the exterior ramp to the main door which hopefully is at least 32" wide. That will take care of the immediate need. Then, it could be covered for better winter accessibility. Of course this is assuming there aren't other complicating factors with a front entrance approach.
The key to any project is organization. This means having adequate materials and tools already at hand before the work starts. Crew tasks should be broken down into manageable chunks. Be sure to have folks with adequate skills on hand. That will likely mean someone with plumbing and electrical skills. And someone with tiling skills. Be sure to have realistic time estimates and not too many bodies on any specific task.
