May I request you to please provide me detailed requirements of your App, at least high level features or similar example App from store?
Please check our past history, reviews & ratings from Freelancer website https://www.freelancer.com/u/leadconcept.html
Please ignore the bid amount, as I still need requirements of your App to estimate precisely.
Look forward to hearing from you & start further discussion thru' private chat.
