Looking for supplies (Modesto)

Hi there.
A friend and i are planning to go into senior homes and bring games and activities like bingo, raffles, auctions etc etc.
were in search of all the supplies we can before we spend money on new items.
Were open to ideas if you have something that you think could be useful.
Were also looking for “prizes” and such to give them for playing.
Anything helps.
Thank you!
