Ashley,
I'm not a big fan of rhetorical questions ... "Want to spend less time writing ...?" The people you are asking already know they want to spend less time writing .... so what's the point asking them?
Just assertively name your skills and services. "I am a writer with a background in biology who can provide you with ..."
Then tell people what they will gain from hiring you. "You will be able to spend more time in the lab and less time at your desk."
But that's just me. Some people like rhetorical questions -- not me. I think they waste people's time and sound like a cheap, late-night television commercials,
That said, I think in your first sentence you use the word "then." Tsk, tsk. Be a writer. The word you want is "than." The word "then" signifies a place in time. The word "than" is used when comparing two things. "This is better than that."
Lastly, when you say "Biologist with data visualization, research and writing experience," you are, essentially, asking the client to choose what you do or what you want to do. That puts the onus on your clients -- like walking into a store and the proprietor says, "I can fix your car or sell you shoes -- what do you want?" The client is going to think, "I want you to tell me what you do well, not ask me to decide."
That's how freelancing works best. Yes, people will hire you for random contracts if you just say "I'm a smart person ... what do you want me to do?" But freelancing works best if you say, "I am a writer who specializes in biology and academic wriring involving natural sciences ..." or something like that. You'll get more work with that approach than with "I'm a biologist who is available for all kinds of things ..."
All that said, Upwork has a policy that forbids helping students with their academic work. It's considered a form of enabling -- helping do someone else's homework. So, you might want to check out that policy and make sure you aren't putting yourself at risk here.
Hope this helps.
