Hello Sir,
I read your requirement and I would like to know more about same.
Let me introduce myself, I am Angel, having 8+ years experience in mobile development (Android & iOS) and I can provide you perfect solution on or before time for all your requirement and I can develop high quality code in the cheapest rate in market.
I am desperately looking for work, actually I can even make you this app less than what I quoted (freelancer can't allow me to quote lower than this, as your lower limit is $250)
And of course you can pay after you satisfy with my work :)
Please let me know suitable time for you to discuss more on same via chat or other preferable.
Looking forward for your positive reply :)
