Ok just guessin at it being 3 and a half feet tall from the ground to the porch I came up with 600$ in materials assuming it will be just a straight ramp,then i still have to figure for it to have a landing at the bottom and if it cant be in a straight line another landing midway and maybe two landings if he needs it to end up at his sidewalk coming from one side of the porch???????...so two landings if it ends up back on the front sidewalk....found a site from the ada that gives all specifications on slope,width and railing heighth's size of landings etc.
