Not sure if its just my server but seems to be a lack of decent healers at the normal raid level and up.
My guild is really having trouble finding that second healer to go along with our Monk who just pretty much destroys everyone she is paired up with.
You're on a high pop, top progression realm. I really doubt your server is lacking decent healers.
Since your guild's progression is behind many of the others on your realm, it's going to be harder for you to attract anyone, especially the better healers that might have options for getting spots in guilds more progressed than yours. This might mean settling for a less skilled healer who will get better with some experience and gear. Considering the size of your guild, I'm surprised you don't have such a healer already in it and waiting to raid if you'd just give them the chance.
Frankly, this is probably the most accurate answer considering ur on area 52. There's healers there, you just haven't found them, and as the gnome says, it's probably related to your current progression. No offense, but if you offered me a raid spot right now, I wouldn't take it either. I seriously am in no mood to do progression on garalon or sha of fear when my current guild has those basically on farm.
Instead of waiting for some magical perfect healer to fall in your lap, I think ur gonna have to change your priorities. Rather than looking at their NUMBERS, check their attitude: are they enthusiastic? Do you think they will be dependable? Do they follow orders? Even if they aren't doing very well, do they acknowledge it, and can u seem them actively trying to improve? When the answers to these questions are yes, take that healer regardless the numbers because it will pay out in the long-term.
If you maintain a current strategy of just getting a pug and then hoping that pugger to be really good, then you'll probably need to KEEP waiting cause when you find a healer that's really good, that same healer probably has a pick of 2-3 potential teams they could join.
Just like less skilled players seek out lower ranked guilds that match their skill level better, u are going to have to be satisfied if less progressed or even fresh 90 healers with the hope that they will develop into something better.
Right now, I think you only look at recount to decide if a healer is good or not, and that's probably why you are having so much problem finding a healer.
