Hello…how to start a freelance work regarding internet marketing? is there any site?

My brother is planning to fetch business through internet marketing, can anyone suggest him which company will be the best to choose for?

I am prejudiced in using internet marketing for small business. I own a brick and mortar store but I want presence online too. Does anyone have any ideas? Gratitude in advance…

I was just wonderstruck what would be a good source for idealistic ideas for starting an
internet marketing business? Any help would be valued.
