What minimum resources are needed to start outsourcing to small and medium-sized businesses in the CIS and the West?

Question

Programming

Hi all !
I would be grateful to everyone for the answers to the following: I
worked for several years in a web product company and a small web studio. He was engaged in attracting customers and developing relationships with them, partly in marketing.
In the future, I want to open a small company for the development, integration, customization and support of software, web and mobile (maybe something else) for small and medium-sized businesses in the CIS and the West.
Basically 3 questions:

1. What is the minimum number of people needed and what skills do they need to start the above activity?
   
2. Given the small number of people at the start, what projects can be carried out?
   
3. Perhaps someone knows blogs, resources, useful articles on opening the above activities (I used the search, but I would be grateful for additional information)?
   

Thanks everyone for the replies!

Answer 1

"Engaged in attracting customers and developing relationships with them, partly in marketing."
"Tell me, what is the minimum number of people needed and what skills do they need to start the above activity?"
Sorry, but some mutually exclusive paragraphs.
To get started - you must be able to find and attract a client in order to sign a contract and receive money.
Everything else is needed to keep the client, to get more money, to get more clients later.

Answer 2

If you think that you worked in a successful company, then copy its structure
If not, look for a successful office, work in it, then copy it

Answer 4

The bare minimum is you (advertising/customer search) and IT. You find an order, they implement it. The rest is understood and hired in the process: lawyer, accountant, project manager.
There is a saying - 1 to those who came up with, 10 - to those who implemented, 100 - to those who sold.
I'm waiting for your answer in a personal (see comments on the question) - I have a plan in the same area, I'm just looking for a person like you (I myself am more technical)
