Enhance pre-existing texting app for Android

Hello Folks, I hope you don't mind if I get straight to the point. I already have an app that does the following... o Splash screen o Main control screen - 6 buttons, each when pressed sends a particular SMS command to a unit number, which is set in program settings o Settings menu - App password (set and saved locally, but needs encryption), unit number (number to send texts), and check box to remember password o Activation screen - Main control is disabled/grayed out with one large, green 'Activate' button, which involves setting the password and the unit number ...and all SMS messages it sends do not show up in the phone's texting application, as desired. And I'd like to make the following upgrades: o Add a “Change Password” option to Settings menu o Add encryption to the local database (or at least the password field) o Add images to make the buttons look depressed (images provided) o Add click sound (provided) and vibration to button taps with the option to disable them in Settings menu o Make the logo in the footer a button that launches the website o Add support for user-selected themes (different images for buttons; images provided) o Command-sent-successfully confirmation message on control screen o Add scheduled-commands functionality to the web server, which is also an SMS gateway o Intrusion detection system (After X many failed login attempts without a subsequently successful attempt, send an alert SMS to the alert number stored in the Settings menu, which is pre-existing.) o Add sound (provided) that plays as splash screen loads If this is something you or your team can do, I'd love to hear from you.
