Hi, it's my great honor to send you a mail about your project.
I have read everything carefully & interested to discuss further.
If you allow my proposal, I am trying to make free Demo website only with User Interface for you according to your demands.
What I want to say is that I am flexible in price and quality & long-term relationship is more important for me.
And even I have a lot of experienced about Mobile application, as your project is first for me in freelancer, I will build your application fantastically with my team.
Look forward to hearing from you.
