2 Part Fix On My Wordpress Website

Please accept this only if you have great experience in PHP, CSS and HTML. My Wordpress website has been heavily customized. The details are a little long and is just for reference to make you understand better. My website: [login to view URL] Here is what I need: 1. Add a sorting filter for all event listing, on category and search results page. Example concept taken from airbnb: [login to view URL] It should function like the link shown except with some customized fields based on my image. Design should look 100% same as my image and functions same as "airbnb" sorting. Refer to Image 3a. - Once user scroll past the red line, the highlighted part will be sticky to the menu and also a button Filter will appear. Refer to Image 3a and 3b. - Add custom "Event Type" field as shown in image. This should appear in Submit Event Page in frontend and backend submission. This should function with filter to display correct events. Refer to Image 4. 2. Few mini fix - Implement scroll to load more events for Search Results page: [login to view URL] Now it is using pagination. This is already coded but its functioning for other page only. It should show 15 events and when user scrolls mid way it will show another 15 more. - Upload Image in Submit Event page has issues. Change the hover cursor for the Upload Image button to hand. When I try to arrange the images in order (by draggin) in Upload Image, the area becomes weird. Need to fix this. - Wishlist in homepage for spotlight, featured and our picks area and in related events area. (Wishlist is already coded) - When I open the search popup. The background item seems to be moved such as the menu and the header. It should display as normal. - Consider This Event As and Price Packages field should be saved into other repeating events when created. Now other fields are passed to the repeated event except this few fields. - The login/register popup now is able to scroll and drag. Set is so it is not scrollable and cannot be drag left or right. - After selecting Start Time, the End Time will automatically popup in event submission, similar to start date. - In Submit Event page at the Select A Package Field, paid package now will open up additional options. I want to set it automatically those options are enabled and it will not display the additional options anymore. **Payment will only be released once all points are completed perfectly. Point 1 and 2 will each be 50%. No release until the points is completed.
