Search plugin with appointments

I'm looking for someone that can integrate or implement a new plugin that will work in a wordpress site. It is a web search that will integrate the wordpress theme with one appointment plugin. It should works as an website search for hotels, as example, it means that user should find a company by location, category or name (it´s implemented with the wordpress theme ) and also have the option to find by service, price, professional, day and time (these options are available on the appointment plugin. When user find a company with a free block according to the desired search, he can select and complete the appointment. The data base structure should be the same and currently the appointment plugin is not work for multi companies.
