Wordpress custom script theme fixing

Hello, in this project i need someone that can help us to do this 2 tasks: Using plugin Advanced Custom Field i created some additional post type, and i have a custom script that i use in front end to SEARCH and DISPLAY this set of custom post type and custom meta keywors. 1) i need to migrate the existing script from old theme to a new one ( the script actually is inside some custom pages template file and some file ( previous developer did a big mess on files ), the new theme is using Twitter Bootstrap and offer full set of styled components, we wanna use bootstrap ready component to give to the script a new nicer look. 2) we will need to do some fix to this existing script to make it fully working ( we had to do some changes adding some new custom fields and actual script must be updated to come back at work as before. Our budget for this FIX + template substitution is 100 USD
