Estimate for Restoring Brick Facade

I am looking at a brick three story house with a painted brick facade. What would be a reasonable amount to estimate to restore the brick facade including the front stoop area. I don’t think any significant structural work changes will be needed, but there will likely be need of some repairs, patching. I would likely want to strip most of the paint off entirely and restore the natural brick color (so I would not just be adding another layer of paint). It is a landmarked block. Thank you!
