Cost Segregation Study Firm Recommendations

I have a couple rentals near Milwaukee, I'm looking to do a cost segregation study to accelerate depreciation and recapture some bonus depreciation from the last few years. Im going to be claiming REP status for my 2025 tax return, and am hoping to deduct everything I can against my W-2 income for a nice tax refund.

Any recommendations on who can perform the study and what it would cost to have done on a duplex? Is it a niche trade? I'm a novice with regards to these, looking for a good place to start.

thanks!!!
