Dear, Manager.
I have read your post and think I am a suitable developer for you.
I am an expert on mobile development with more than 4 years experiences.
I am very much interested in your project .
I can finish your project faster than any others.
If you are looking for a developer with full experience and long history on only this marketplace, I am not a right person, but if you are looking for just talented and reliable developer, I am a right person for you.
Nobody was disappointed with me.
I hope we grow your idea to awesome app together.
I have some questions about your project and want to discuss about it.
I am always available on Email and Skype. I work more than 30 hours per week and able to start your project as soon as possible according to you.
Thank you for your consideration.
Best Regards.
Andriy.
