hi can you make the payment guaranteed. I would like to work on this project

No, unfortunately we are not able to do so. However, our intent is to choose the best design out of the designs submitted, and it is highly likely that we will select the best design from DesignCrowd.

Hi,
Thanks for the invitation.I'm working on your project and submitted a design.hope you'd like it and will give a feedback. cheers

Will you be providing feedback to designers?
