My advice with recruiting is to be up front with people. Make people abundently aware of your policies, how the guild is run, what the aims of the guild are and above all look for people who have a personality that matches the guild. One bad seed can ruin the entire crop so make sure you recruit selectively.
Okay onto answering your question rather than giving guild management advice. There are a number of in game mediums available to a guild trying to recruit, being a new guild I would advise first running pugs and recruiting thos good players you run with, provided you lead well and they aren't happy to stay in the guild they are in this can be a good way to pickup new members (heroics are normally better for this as most pug raids of lower end naxx will have a large volume of alts in already established raiding guilds).
Make sure you live up to the expectation you planted in people who are already in the guild, provided you outlined these clearly that is, e.g. if you promised a 10 man run every Wednesday at 7pm make sure you run a 10 man every wednesday at 7pm, even if you have to pug people to fill the gaps to begin with people will stay if you are meeting the requirements.
This may not apply to you so much but if you have a DKP or attendance system make sure that this is always updated or in a position where you can update it quickly. People like to know what their current standings are.
If you have guild officers/class leaders schedule a weekly meeting with them on vent. It doesn't have to be very long, however I find that these short vent meetings help greatly when managing individual concerns and maintaining guild direction and systems.
Gah sorry veered off track again.
As for guild recruitment mediums since you are aiming to be a more casual guild you want to focus more on in instance recruitment (i.e. approaching good/compatible players you come accross in runs) and trade/general spam. Most casual players won't be visiting things like the wow forums as regularly as those raiders looking for high end raiding guilds, however it never hurts to post in them or other wow related sites, like tankspot
. Make detailed recruitment posts, don't overdo it though only include the required information that will bring in the kind of person you are looking for. Take a look at some of the recruitment posts here and mirror some of the common themes, most important things with these is to outline your aim early in the post.
Successful guild management is hard work, do not enter into creating a new guild if you are not prepared to put time and effort into it. Most new guilds collapse because their respective GM's where not aware of the amount of work guild management requires and subsequently neglect their duties or have a meltdown. So make sure you are prepared to do the work, and it won't always be pleasant, before you get in too deep. Having said this there is a very real sense of reward in creating a successful, fun, stable guild so provided you can get through the formative stages and lead well you will do well.
Anyway I sort of veered off on a tangent a few times here but guild recruitment very closely ties into guild management, it's one thing to get people into the guild, it's a completely different story when it comes to keeping them in, have strategies to retain players.
Anyway best of luck and I hope this helps you get your recruitment right.
