The guild my main (rogue) is in is a fairly serious raiding guild, but we only raid 3x per week, the least of all the top 15 raiding guilds on my server. We raid the fewest hours. We keep up with guilds that raid 32 hrs a week, while we raid 12. We have a set schedule and attendance requirements. If you don't meet the attendance requirements (which is 75% of the last 60 days raids), you can only bid/roll on something if someone who DOES have the attendance doesn't want it. We never will DE something that someone can use, but people who show up reguarly get things before those who don't.
Required raids are progression raids and only those count toward your attendance requirement. There are often other raids that happen, but those are not required and do not make use of DKP for loot distribution (with the exception of certain items, such as Dragonspine Trophy). We do not kick people out of the guild who don't meet attendance requirements, they are just bottom of the loot distribution tree, and the least likely to be invited to a raid when we have enough people who normally attend. We have only 65 accounts in my guild and raid Black Temple as pretty much our only progression raids at this time, but these rules have been in place since the Naxx and Molten Core days (though I wasn't in the guild then).
As attendance problems develop or if we have to call more than 1 raid in a month due to attendance issues, we recruit people to fill the missing roles.
The new guild my paladin is in is planning to raid Gruul's for the first time on Sunday. I'm pretty sure if the raid is short people, we will be pulling people from the guilds that some people's mains are in to fill the empty spots. If you can't quite get together enough for a full guild raid, consider pulling experienced players that are friends of people in the guild and letting loot go to rolls. While you will ideally want to get full raids of just guild people, you can often prove that your guild can handle that content by downing those bosses with a few ppl not in the guild.
You can't make your existing membership interested in 25-mans. But you can make it possible for those who are interested to do them and recruit people to make up for those who don't.
