Kindly use buyer request.
Thanks for your kind information. But I do not get any good feedback by this. What should I do to increase my sales???
Make your GIG attractive and showcase your portfolio with eye catching design etc.
Buyer request is also IMP. Make sure when submitting any proposal your content is more Eye catching and crystal clear so that buyer directly contact you.
First, you create a perfect gig with attractive Thumbnail, gig title also tag is very important, then you share your gig in some social media, hope you will get good result
