Hi Sir,
We are working in your project.
It will be great if you make the project guaranteed.
Thanks

This sounds like a very interesting project that I would like to work on, but unfortunately the payment is not guaranteed. Making the payment guaranteed will draw higher quality designers giving you a better chance at receiving more quality submissions. Guaranteeing the payment shows that you are serious which means the designers will be more serious as well. If you decide to guarantee the payment please let me know.

Hi Project Owner,
Will you accept .psd(photoshop files) as final deliverable? and can you please share your email address?

Thanks & Regards
Hazel
