Port Android App to iOS

Hi, What budget would it require to have you port my Android “Diary with lock” app to iOS? Please see: https://play.google.com/store/apps/details?id=com.adpog.diary&hl=en No all features need to be ported. Minimum version should include – Splash – Note list – Write/edit Note — Signup — Login — Forgot Password — Change Password — Delete Account — About this app — Personalize (change background and font-color) — Configure code lock — Export entries to flat .txt file (for sharing with email)
