I agree with Dunster, it may not be practical. Homeless don't really need lap quilts, they need larger ones like sleeping bags. Here is a link to the sleeping bag project-

Money being an issue might make it even harder. Even if you buy old clothes at Goodwill, it still costs money. Plus something for the batting and backing-I guess old sheets would work but you still have to buy them. Unless you've gotten a lot of donations, but it usually takes time to develop a network for donations.
Have her check her local freecycle group. She may be able to get a lot of donations that way. Garage sales at the end of the day-people may just give her bags of stuff so they don't have to put it back into the house.
Maybe make large tote bags with a small pocket for the bible and add some toiletries or food inside the bag. Call around different designs stores to see if they will donate their old samples.
