Hi there..
Really interesting project and I am glad that I am participating. I am working on the design and hopefully you will wait for my design before choosing the winning design.

I have some questions about the design so I can make the perfect design that you are looking for. And also I have some offer to you, so please can you send me a private message?

Looking forward to hearing from you, and having further cooperation.

Best regards,
Igor, GDS Team.
