I am new to Upwork but have completed my profile, taken tests relavent to my speciality and am submitting proposals daily. I have not received a single reply. Even for a job that is identical to what I do full-time. Can you please review my profile and let me know if something is missing, unprofessional, etc.?
Since you don't have any work history on your profile yet, try adding some names of places you've worked, if you can. If you have a blog or anything else relevant to your field, definitely link that. The first few are always the hardest - they'll roll in faster once you get going.
Best of luck.
