Background for Question

My mother owns 2 beat up properties in Mexico and I want to fix and flip them. I also want to do other fix and flips to resell and/or hold as income properties. Through networking, I was put in contact with a business, legal, and tax consultant for US-Mex business who seemed pretty knowledgeable over the phone. However, his business proposal prices alarmed me. I am just starting out in real estate. Below are screenshots of this prices.


Is the below information accurate? Are these prices about right for an American to do real estate business in Mexico? Or is he trying to rip me off?

Thank you in advance!
