My name is james and I have been working as iphone/android developer from the past 5 years. I have developed many apps for my clients like this before in the past, i have a great experience of google maps, geolocations etc for reference you can check my portfolio, that's why I am interested to work on your app as well. I have gone through your project details and I can do this app very easily. I am available to start on your project immediately. This is why I would like you to provide me with more details so that I can get started on your project.
You can have a look at my portfolio, reviews, completion rate and the apps I have developed so far. It will give you an idea that why I am the best for you app :). For sure no one can provide you with the below four things I can provide you which are
1) Quality
2) Innovative ideas (Affordable cost)
3) Availability
4) Excellent Communication
i have few questions for you
1) will you provide the design for the app?
2) do you want this app on both ios and android?
3)do you want CMS for this project?
