Welcome to the upwork community.
How long did it take to you to get your first job?
For me, it tooks 4 months, but if you are lucky, then you will get it in your first try. Who knows?
How your cover letter looks like?
It's always different than the previous one. The truth is, I don't remember what I wrote in my last cover letter also I didn't even know what I'm gonna write for my next one. It's always came from somewhere when I started writing it but when you are going to write a cover letter for a job, my suggestion is, be gentle, be confident and be honest.
And what would you change about my profile?
Your profile is not 100% yet. complete the suggested steps. Just took some tests, add some other experience if you have. Portfolio if possible. Maybe someone else (data entry expert) can help you with that. I am no expert in this category.
Good Luck and Thank You..
