Customise Wordpress site | Angular Theme

It is a Real Estates website...with Properties added as portfolio entries. I use Angular theme as the main template...and i would like some help with some custom dynamic elements: 1. An advanced search module with Region and Price filters (Region, Price, Code, Area, & Region are Portfolio meta information) 2. Create a (custom) field in the admin panel for all portfolio entries, that turns ON and OFF an image/icon/layer tag on the front end (like "SOLD" or "UNDER OFFER" ...next to the image of each Property / either on the Single Page or Portfolio view ). 3. Associate a different color for every one of the 4 main categories (HOUSES, LAND, BUSINESS, RENT)...so that portfolio entries under HOUSES appear with a blue tag, LAND with a green and so on... Some minor extra help with PHP might be needed. Portfolio and project demo page: [login to view URL]
