It's an easy fix bro, also you don't need to pay anyone just to get accepted into upwork, lol. I got the same message some time ago. Don't be lazy and try to make a decent looking profile: try adding some highly valuable skills, something with programming or AI, we don't know what you specialise in, so we can't say exactly what to choose, but try finding on upwork other profiles that are related to your work-category and try making your profile similar (don't forget to add some education and past experience - even if you don't have one, it's very important, make it up, but don't go overboard), also add nice photo and most importantly - write decent descriptions wherever they ask nowadays. I'm sure you know what CV is and important it is in todays world, so try to make your profile look as good as you possibly can!
Let us know how it goes for ya!
P.S. Getting profile accepted is the easy part, the hardest part will be sales, so be prepared to hustle - you'll need to get reviews/testimonials in order to win jobs on Upwork.
