Hi Awais,
You may want to check the help articles listed here to help you create a job post in the Upwork marketplace where freelancers can submit a bid/proposal for your job.
Once you have posted your job, and you feel that you need further help with shortlisting freelancers for your project, you can come back here, and let our team know so that we can connect you with our Talent Solutions Team.
