Wordpress Theme Customization

Hello, I have bought a Wordpress Theme ( Auto Stars - Car Dealership & Listings WP Theme ) from envatomarket ( Themeforest ) . This Theme i want / need to customize more. There is a few modifications i need, please give me a Price for each Feature / Package Price for all together. 1. The Homepage: I want a homepage which is similar to another site, i can provide the link in private message. But the site should include all Car Bodytypes with images, and all car makes. Should as well show a counter behind each make and bodytypes too show how much cars are already in this category. 2. Ad Listing Page: I need a red star " * " which is behind all mandatory fields. If users forgot to enter a mandatory field i want the site automatically go/jump to the field which they forgot to enter, and to show a popup or something which says " You have to fill out this field ". If you look at the Add listing page you can see its splitted into 5 Steps. After each Step there is a button which Says " Save & Continue " . Each time a user press this button i want that the site automatically scrolls up to the top again. 3. Breadcrumbs: If you go for example to the search and search for cars, it should make breadcrumbs for the searches u make. For example i want be the breadcrumb like that: Mysite -> Cars -> Toyota -> Carina Then if they press on the " Carina " it will go back to the Search page and show all Cars which are Carina, if you press on Toyota it will show all Cars which are Toyota, and so on. 4. Advanced Custom Search: I want a more advanced custom search, i can show example from two other sites via pm. Thanks so much! :)
