No idea if there outfitters in the area but there are good numbers of elk in and proximal to farm / ranch land in SW Alberta. perhaps there might be some no horses / minimal horses options.
I second the suggestion of SW Alberta.
I would also look at the Peace Country in northern Alberta.
There maybe some good hunts in the Parkland region as well. Elk are expanding into new areas across the province. Does the outfitter you used for your deer hunt guide for elk as well? IIRC that was in the Parkland area.
We have a good number of elk here in SE Alberta now but I haven't heard of anyone outfitting for them here yet.
This is mainly due I believe, to the fact the herds regularly move in and out of the military base which while there is a "hunt" on it, is only open to residents on a draw basis.
Daniel, as you know, I live, work and play in SE Alberta and I am holding off cashing in my draw points in this region due to fact the elk, esp the big boys, don't venture far from the base. FWIW there have been some excellent bulls taken in the area outside the base though. I wouldn't recommend basing an expensive trip here....yet. I suspect things will change as the herd matures and disperses further in the SE.
