As a wordpress designer, is it possible to have an important number of clients "online"?

Hey guys,

I'm learning to use wordpress, and in general the science related with creating great websites, graphically but most of all in terms of user experience, and in terms of conversion rate.

I can kill two birds with one stone.

First.
On the midterm, this allows me to get fundamental knowledge I'll be able to use personally, with own businesses.

But I need funds, first. Which brings us with my other incentive to get into WP.

I have a student loan to refund, and I need a short term way to generate revenues.

I know there is a huge demand for different small businesses, needing a website.

I can go out there and get clients face to face if I have to.

But, do you have experiences in engaging in full remote work relationships with clients?

What I mean by that, is finding clients, through online strategies (mails, social medias...), and working remotely with them?

I know personally a copywirter, freelance, that is succesful in getting clients online, and working fully remotely with them.

To get clients, he doesn't even do no "cold calls", ( after being tired of dealing with unpolite people for sometimes)

On the long run, it would be way less draining.

If you have valuable insights about it, it would be very appreciated.

Thanks,
