1.) You’ve managed to misspell both “academy” and “development” on the front page of your profile. This doesn’t inspire confidence.
2.) Your “vibe” (as you call it) definitely makes me see you as the guy who organized a party, not a hardworking student putting himself through Vet school. You need to be less casual about your language - you’re not asking someone to have a beer with you, you’re asking them to hire you.
3.) For your one gig, it’s “on fire”, not “one fire” - and even in this context, it’s grammatically incorrect. “Dedicated” would be a considerably better fit, unless actual combustion is part of your longterm work goals.
4.) It’s Fiverr. Two Rs. If a client can’t trust you to get the name of this site correct, how can you expect them to trust you with attention to detail on their work?
5.) I’m guessing this is a language/culture translation issue because I see it often on Fiverr. When you use a comma ( , ) there always needs to be a space after it. If I’m writing a list, I wouldn’t say apple,orange,pear - I would say apple, orange, pear. When the spaces between words and punctuation vanish, it instantly gives content a slapdash, poorly-put-together feel. Not the kind of impression you want to make!
6.) Think about attracting a client like attracting a cute girl (or boy, it’s 2019!). Desperation isn’t attractive - you need to project confidence and an impression of, “you can hire me, and it would be a good choice, but I’m also okay if you don’t.” When you desperately chase sales, just like when you chase girls/boys, what you catch is probably not what you actually want! Good, stable clients respond to calm attitudes and professional language and demeanor, not an overly-excited, exclamation point-riddled sales pitch.
