Instead of just waiting for the new order, you can invest your time in understanding Fiverr and polishing the skills you have. I recommend you the Online Freelancing Essentials: Be A Successful Fiverr Seller. It is an efficient and free course to understand the Fiverr marketplace and how it works. It will help you. You can access that course from the following link: https://learn.fiverr.com/courses/online-freelancing-essentials-be-a-successful-fiverr-seller
Have a nice day!
Congratulations on getting the first order. Be prompt in replying to the clients. You can tell your clients if you offer multiple gigs and can ask them politely if they need them.
I think instead of editing the gig every day, you should do some proper research and all the work in one go and then create the gig. Editing the gig, again and again, would not help.
