Hi,
First of all I want to tell you that I have knowledge of android platform only so this bid is only for android app in given time period,
Coming to the point, I am not gonna tell you that I am the best for this job but I can assure you that I am going to give my 100% to this job if I get selected. It is true that I haven't done freelancing before but at least on some point, I am going to start so why can't it be this project. You can see my profile or I can even send you my resume so that you can get assured that I am capable of doing this job.
Hope to be in touch with you soon.
Thanks,
Vaishal Shah
