Hello! As a new graphic designer on Upwork, setting your hourly rate at $3 might not be advisable. It's important to consider the value of your skills and experience when determining your rate. A rate as low as $3 per hour may give the impression that your work is of low quality or that you are inexperienced.
I would recommend researching the typical rates for graphic designers on Upwork with similar experience and skills as you. Setting a competitive rate that reflects the quality of your work can help attract clients who are willing to pay for your services. Remember that it's better to start with a rate that you feel comfortable with and then adjust it as you gain more experience and positive feedback from clients. Good luck on Upwork!
