I’ve been trying way too hard to get customers but still no luck.
I got my first sale 2 days ago, from buyer requests which is probably my main source of traffic and the customer gave me 4/5 stars.
I’ve done everything I can, advertise on social media, youtube, forums. Still no luck. this is really hard.

After I got my first sale and this is what I am now.

I’ve been advertising my gig in facebook groups that could have potential buyers.
Who do you think are my potential buyers?
