Need changes to a Mobile Game template

I recently purchased a template for a game and now need some minor tweaks to the code to get it ready for my custom graphics. What I have: A top down shooter game template. Similar to space invaders... I am trying to manipulate the game enough to make it my own with custom graphics. I am turning the game on its side "literally" to have enemies enter from the right progressing to the left while the player remains on the left side shooting the waves of enemies coming from the right for each level. What I need: A main menu screen with Play, Options, Store, Credits buttons. Right now it just jumps into the game after 2 images showing logos. Need to divide the waves into 5 "worlds" with 4 levels per world... 20 separate levels all together. I basically have 5 backgrounds to represent the worlds and need those to change as we progress in the game. Need to introduce a new set of enemies for every world.(all artwork is done for this) Need to automatically start a slideshow in between worlds to tell a illustrated story. (2-3 images that transition to the next before the next wave starts) No graphics will be needed for this... just the code working like it needs to... I should be able to handle the rest. I can provide place holders for everything to help you work. Please respond with COCOBEAN in your message so I know you read this whole description. I am looking for someone to knock this out with me ASAP... I can discuss further on skype and also share my screen to show the templates code that I have... I will hire immediately if you know how to do everything I listed. I don't have a huge budget for this since I purchased the template so a skilled programmer that understands exactly what I need would be preferred. If you are good enough I can get started with you today... no need to wait for bids if your good right?! Lets get started!
