Hello! I believe we all go through a similar situation when starting out. I would recommend that you focus heavily on your portfolio; since your services are related to graphic design, it needs to effectively showcase your abilities to potential clients.
Similarly, I suggest working on enhancing the covers of your gigs by incorporating more mockups, such as logos applied to various products like stationery, signs, business cards, etc.
Lastly, I advise you to be patient and try to incorporate your main keywords into the titles of your gigs, your description, etc.
I hope everything goes well for you!
