Although there will be a small cost, it can be effective to have some items made up to give away, or to leave in recreational areas to advertise the group. Items that have been used are coffee mugs with a Christian saying on the side (example here), coasters, pens, or even small soft toys or mascots. If designed to be attractive and interesting these can be good conversation openers. You can find a range of options on the internet, under promotional products.
