Data Recovery Business Plan

starting a data recovery business
I am thinking about starting a business where I take failed hard disks from people and try to retrieve the data for them.
I am not an expert on this but I plan to hire someone who has the skills and abilities to perform the needed tasks.
In my country, we have a high number of users but we don’t have such a business.
What are the tools that I will need to get things started. Do I only need a few PCs with recovery software and I am set? or do I need additional equipment? Are they expensive?
You’ll also need a clean room. Yes, they are expensive.
