Dear Employer,
I am a mobile app developer team manager and a developer myself too. Our team consist of highly experienced mobile app developers who have consistently delivered projects on time and within budget, which has earned us many positive ratings, as you'll see in our work history.
I have gone through the project description and understood the overall requirements.
I am available to discuss this further via freelancer.com chat tool, and would be happy to set up a convenient time to discuss the application you're moving and some ideas about the safest way to get it into the cloud. We are available to commence this project right away. Looking forward to your response.
Regards
Sam
