I agree with everyone else here, your username does not seem all that professional. Like @english_voice noted, I too would probably seek to work with someone else – someone more relatable. As a brand developer myself, don’t go for techy-cool… always find (and develop) something that relates to the target customers you are trying to convince to hire you.
In addition, the fact that you have only one seller review, and it’s a 1-star “failed to deliver on time” review, is probably turning off a lot of potential buyers. You have a visually-terrible seller reputation (which can always improve, mind you), and a hard-to-relate-to username. The people you seek to have hire you, are probably choosing to hire one of your many competitors.
