How I can start my own Bookkeeping Business?

I am an Accounting student and I am planning to start my own Bookkeeping services.

I have a few questions

• How I can do start my business from home?
• is a professional degree (CA, ACCA) necessary for a Bookkeeping business?
• What sources I can use to get customers?
• Do I have to start with Freelancing websites or have to launch the business office directly?
  
  I am just looking for expert suggestions who started from zero and become multinational companies.
