Does anyone have experience with due diligence on machinery and equipment?

I'm considering a manufacturing company and I need to hire a firm to do an assessment of the condition of the equipment in the factory. I come from the finance industry and this isn't a skill set that I have. I'm not looking for a valuation per se, instead, I need someone to tell me if its all in good working order and what will need to be replaced soon. Appreciate any referrals to firms that can perform this service.

Thanks,
Rich
