The daylily club here struggles but the iris society is doing well. Two things to consider when you get your club formed are an annual show and a sale/auction. Both can help to get new members. We have 2 shows in May. A local radio station gives us good publicity and we take flyers to local nurseries. At the sale we have plants provided by members.....mostly older cultivars which we sell at a good price. We get good attendance from the public. The auction held later in the day is attended mainly by members and features newer cultivars provided by members and also some purchased by the club from favorite hybridizers. We send them a sum of money and they are usually generous. As to speakers, members can be a good resource as speakers sharing the way they grow dls. Good luck.
