I don't know if your package includes a cake, but I was approached to provide a "budget" wedding cake for a venue who are offering what my daughter calls "wedding in a box" packages, they also offered me the chance to exhibit at their wedding open evening .I don't know if this is something you could incorporate?
Also the open evening was a bit different to a wedding fair, they had about 8 tables set up in different styles and had got florist, chair covers, stationery, favours and cake suppliers to contribute their wares to match, they had a dj and drinks and canapes for couples and special offers from all the suppliers and the venue for anyone who booked their wedding on the day, it was good to see the tables set out and they got quite a few bookings too
