Customize 100% Open Source Business Review Script

I need a 100% open source script customized. The script is called www.meeplace.com. I am only asking to have a couple of small modifications done first. IF...... the programmer selected does a great job with the first (3) small modifications, they will get the rest of the work on the site to include regular maintenance of the site when needed. There is alot of mods that need to be done to include mobile apps. Here are the details for the first (3) "test" modifications: 1) Integrate the custom design. 2) Customize the business profile page to include "pictures and videos" and a "printable" coupon. 3) Customize the "events" section by adding a 2nd events listing. One events page comes with the script (popular events). In addition to that events page, we need a second events page. These are EASY modifications. If the programmer selected does well on these, they will get the rest of the work. I have NO PATIENCE for programmers that over state their experience. Please only apply if this is very easy for you. Thank you, Chad
