How to get order ? Please give me some advice
There is a number of threads on this already so I suggest you go check those out for tips.
In terms of your current gig though, I would change the title to be more clear and concise. Run all your text through a grammar checker to assure there is no grammar mistakes. You should change your gig image to be more simple and bold, it’s far too busy. I would recommend you use a blue background (as that increases buyer trust), add a mail icon on one side and add a maximum of 6 words about your service in large and bold text.
Hope this helps
Thanks for your valuable advice dude
