Clinical Psychology Review of Workbook/guide/deck

I am looking for a clinical psychologist to help me with reviewing a Print on Demand product I will be selling online. I run dropshipping stores for trending products, and I wanted to start a brand that genuinely will make a difference. The product I created is a workbook, guide, and deck of cards with a focus on productivity and emotional regulation. I took some of the techniques that I used in my own life, along with significant research, and created this offer to help people with something I personally struggled with. I do feel a deep responsibility to make sure that this product will genuinely inspire positive changes in people's lives, and I want to make it as effective as I can. I am looking for someone with a clinical psychology background to review these products - should be around 70-80 pages in total(should only be about 2-3h of work from my best estimate, if it takes longer, I will be sure to pay you for your time). I am comfortable with hourly rates or one-time payments and am willing to pay well for a qualified candidate.
