Hi MD R and welcome to Upwork!
If at any moment you need help with anything, feel free to let us know and we will be more than happy to assist you.
As you are new to Upwork, I recommend checking out the Freelancing Resources board where you can find plenty of articles that we put together to help freelancers to get to a safe and successful start.
At first take my respect,
I am new in Upwork, So I have done many mistakes & also don't know how to become a great freelancer in Upwork, Also I don't know how to set up my profile & cover letter, So I need much more help.
I hope brother, You always help me.
I suggest that you take a look at this Community thread to help you get started along with the Freelancing Resources board in which you'll find plenty of articles to help you with writing proposals, negotiating with clients, setting your rates, enhancing your profile, and so on.
I hope this helps and good luck!
