I assume your tank situation is figured out? Your guild sounds very close to what I’d be looking for, so I’m going to link my “LFG” post here just in case you’d be interested…
In OG TBC I had full Sunwell experience (mt and ot) prior to 3.0. Post-3.0, my guild did Sunwell speed clears (and even did “for the alliance” at lv70, while the faction bosses were all 80+).
Thanks
