Wordpress PHP Modifications

I have a wordpress Real Estate theme. The theme has its own search module but I need some modifications with it. I need some more details to be searched and some areas needed to be deleted. Little bit of PHP work need to be done. Also the theme I have has a feature I need to change. The title of the property has to be address of the property so the google map would work. But I don't want it. I need the titles to be like "2 bedroom sea view house for rent" kind of writing and add google maps from the different source which it can be longitude or lattitude, or even address. Anything else should work. Please let me know if you can do that so I can give you more details about the things to be done. Small things if you know what are you doing. But quite honestly I've couldn't find the related codes. So I need some professional help.
