Meeting dilemma

I have no money at all, and the only alternative to digital marketing is selling products or services. The problem is that I don't have money to sell the product, and I can't sell the service because it would be necessary to have a closing meeting on a call with the client, and I have speech problems, so that's not an option.

What is your recommendation? Is there any way to sell services without the need for a single call? Freelance maybe?
and products? I'm going crazy about this.

Yes, look at this forum for example...there are hundreds of sellers here and not a single one of them had to call anyone to make a sale
