What is your mother language? Swedish? Then stick with that one only and offer English into Swedish legal translation only. That's my advice. Being a polyglot is great but if you sell yourself as an any-language into any-language translator they will not take you seriously, even if you have all the diplomas. There are many translators here and clients look for specialists. English into Swedish legal translation is something very specific and translation into Swedish is not that common so you have an ace there, use it! Place your target there, only apply to that kind of jobs and you'll be rewarded. Later, when you have a couple of jobs done you can offer Polish which is also not common, but at first stick with English into Swedish.
By the way, you have some serious typos in your profile. If you are high-proficient in your field you must be perfect, you can't afford to have those typos!
I just start here for a week. After lots of Connects spends and almost depleted finally i got 1 'simple' job, and you know what? I only write pretty short sentences in my cover letter.
"I'm Aldy, let's do it! Feel free to visit my Specialized Profile for more details and showreels"
"I also attached my recent work based on your needs.."
It was 4:50am when i got my first job. After roaming around on upwork for 6hrs. This client need it urgently. So i submit Cover Letter without much talking..
I doubt clients will read all that long cover letter even if you put links or attachments.. unless if they're asking specifically. In my opinion they just wan't result, cheap/reasonable cost, fast delivery. Just like in real life client. And sometimes they're just connect eaters. Posted a job, and then disappear.
So, make sure to write a simple straight forward Cover Letters, and direct them to your Specialized Profile or any portfolios. Simply describe what they will get. What is your service for this particular project. Give them your best as if the client was you. And my other secret is, at this moment i'm 'collecting' upwork portfolios, so i don't mind pick a small job (but verified) at the lowest rate.. So many competitions here Others could be better, or could be cheaper. You can upgrade your account to able to see the bidding. (but i'd stay on free account for now)
Victoria, it takes time to get your first job, and you shouldn't be concerned yet. But, 30 proposals in 2 weeks is an awfully lot--it sounds like maybe you could be targeting a lot more closely. A lot of us who are successful here bid only on jobs where we know that we have experience or skills that will set us apart from the vast majority of other bidders. Just being able to do the job is generally not reason enough to spend connects applying, since there are usually hundreds or thousands of other freelancers who also meet that threshold.
When I was actively bidding on Upwork, I typically found about 5-10 jobs per month that it made sense to bid on.
