How many project/gig should I upload in my profile?

[artsbd]

Hello. I am a graphic designer. I have some expertise skills in graphic design. If I submit 1 project/gig per skill, it will be 10 projects/gigs. Should I upload 10 projects/gigs? Or 1-2 projects/gigs are better. 
What are the best practices?

I hire a lot of artists on Upwork.

I'm not going to hire somebody without a portfolio, of course.

But I don't need to look through hundreds of portfolio pieces.

I want to get a sense of your style, to see if your work makes you a good fit for my project.

I don't really need to see 10 variations on exactly the same thing.
