Joomla Php development required urgently!

Hi I have a joomla website and am using a component called JomEstatePro. This is a property listing component. Basically, a search form is being used for this. I need to create some extra custom fields in this search form. The component currently has some set search fields however I do not know how to add to these. I am also using a 'rightmove datafeed' with a [login to view URL] script. The process script takes the properties as a zip through ftp. Each folder contains a .blm file with some images. This provides details of the properties. When the script is processed it automatically updates the website. Therefore, the search fields will need to relate to what is in the .blm file. Please can you come back to me asap as I would need this done by over the weekend - so by 9th Jan. Thanks, Marc
