Answer honestly rather than aspirationally. A wrong answer here costs you months.
1.Realistically, how many hours a week can you give this?
Retainer work fails if you cannot protect the hours every week.
2.How do you feel about approaching businesses that did not ask to hear from you?
Every one of these services is won through outreach. There is no version without it.
3.Do you know local business owners, or can you walk into places near you?
Local access is the single biggest shortcut to a first customer.
4.Can you tell when something looks wrong, even if you cannot design it yourself?
Image and ads work is judgement work. The tool produces; you decide.
5.Are you comfortable writing in someone else's voice?
Content work is ghostwriting. If it grates, it will not last.
6.How soon do you need this to make money?
Some routes are slower. You should know which before you start, not after.
7.Do you already know anyone who spends money on advertising or online selling?
Ads and image work need buyers who already spend. Without them it is a longer road.
