Question Looking for Authentic Small-Group Tours in Pakistan

I'm on the hunt for a local, authentic tour experience in Pakistan. Normally, I steer clear of group tours, but for Pakistan, it seems like a practical choice. I'm particularly interested in small group tours that offer a deeper, more immersive experience rather than just hopping from one tourist spot to another. Currently, I'm considering a tour by Ylem Expedition. Has anyone here traveled with them before? Would love to hear your thoughts or any other recommendations you might have for a more authentic travel experience in Pakistan.
