Greetings Mike,
That is an important but difficult question to answer because there are so many variables affecting startup costs. Bob had a list of emails that he sent out covering some of those variables. I signed up for it long ago and found it very helpful. I don’t know for sure if it’s the same list I received but I checked at his website learntimeonline.com and there is a blue signup box on the right side of the page. It says ‘Free Reports’ and has 5 reports for starting a business in the list of things they cover. In my list he covered tools. Sounds to me like it’s the same list I got.
You will also find a lot of posts on this forum covering required tools for both watch and clock business startups.
Good luck to you Mike
Best, Phil
