I have a PC repair business, and it can take quite a while to get started.
Choosing a name, planning your advertising, and learning what forms you need to submit. (LLC, EIN, etc.)
Creating forms regarding warranty (and in my case, a data privacy waiver.)
Creating a website and designing a logo.
Finding invoice software and setting it up for your business.
Making telephone calls to get your business listed in phone books, and spending time on the web getting your business listed in dozens of directories.
And don't forget that you have to shop around for business insurance, especially if you offer a service. (Stick to products!!!)
Once you get it running and you start receiving phone calls, you will find a lot of people who schedule an appointment and don't bother to show up.. or even tell you that they're not coming.
If you're operating purely on word of mouth, you can skip a lot of the lengthy parts. If not, I would expect at least a year to get started... Some of it is simply finding the information you need to know, and much of it is finding someone who is willing to help you implement those things.
