Minor changes in HTML5 Canvas Based Javascript Game.

I have few codes of Snake Games that i have gathered form Github, i would like to have the best of all these 3 or 4 to merge in one single game. For example One game has snake shown in blocks, other has an image for it. I want image. One game shows much smoother movement other doesn't. I want smooth movement. One game play sounds when snake eats food, one game doesnt play sound. I want SOUND. One game shows score and button to Play again, one simply restarts. I want Score to be Displayed. All games are playable from keyboard, i want the mouse click to it too; so that player can click in canvas to move snake around. So in short I WANT SOUND TO ADD SCORE TO DISPLAY AT END RESTART BUTTON AT END LEVELS UPON REACHING SPECIFIC SCORE MOUSE CLICK PLAYABLE FEATURE OTHER THAN KEYBOARD PLAY SOUND WHEN SNAKE EATS SNAKE TO BE AN IMAGE. I need all this done in 8 hours. Budget is 30$
