My friend,
Everyone sends you the same suggestion for your question. To be honest, all are right.
Everyone knows, how complex to get an order. For everyone, the solution is the same.
01. Do research
02. Stay active
03. Write an effective and unique gig description
04. Make your gig image attractive, etc
Other than that, luck is all you need to succeed at Fiver.
So keep trying and don't lose hope.
