OpenCart V1.5.1.3 need to finish up some job

Hey guys, I would like to hire someone to finish off my website. It is actually completed but with some error and i need you to help me to fix it. Also i need to add a few extra thing. PLEASE ONLY BID IF YOU ARE SURE YOU CAN COMPLETE THE JOB I ASK FOR, OTHERWISE I WILL NOT PAY IF JOB IS NOT DONE. Can you tell me if you are good with OPENCART shopping cart PHP code? 1)My last developer developed a serial key system to my website but it wasnt working like the one i want, so i just wondering if you can do a little coding to make it work the way i want it to be? 2)Need to make my search bar to AUTO SEARCH BAR (Auto complete), means when you type the seach bar will auto search for the most relevant products. 3)Fix the button description error on the products, it shows error code instead of "Add to wish list" Also some other minor fix work need to be done on coding. Will discuss more after you reply me. Thanks please reply as soon as possible and it is a urgent job because my website is already running and it need to be fix as soon as possible. Thanks! KenGamer
