Fix my wordpress site to function 100 -- 2

I need to be able to import cars into my site using a simple csv format that will upload them. and All item descriptions must be able to be uploaded. I have a program you just need to fix it.. I need Facebook and all social media, login and function 100 percent on the site Meaning I need to be able to make comments and leave messages and login just like a normal member does and notifications to be sent to the seller of the item. I need my inbox posting of messages and sending of messages to be improved. I need a search set up for woo commerce that people can actually look for products such as fashion, Cooking, electronics, and any other category i make.. I want them to have there own search features like the directory part does. in a drop down format like it is on the classified them portion. Set up the top menus to be one for the shopping area and one for the entire website The business people who list there company for directory listings need there own flow. First they sign up for a package then they go to a special page for them that will allow them to post there information in the directory area. Example for a bank to register on the site they should be taken through a process that makes it easy to sign up.. Let me know what you suggest. The post ad page needs to drop the categories down a lot faster. Example if you press Motors on Post ad page it should drop down automatically. If you want you can look at the code of my old site and see how it was done. I have had this same site rebuilt using this theme because there were issues. The old site had this feature The private information on the post ad page should be a drop down as well. SO it is not always seen. Remake the post ad page to be smoother and not so long. Make it user friendly. Also on the post ad page. Only categories for the normal user for classified area should be available.. All directory listings for business should be taken off of that list. Business should have there own process and post ad page. Make it show the correct image when sharing the website on any platform And I need more stuff that i dont know about.. In the end it all has to work out. Set each category to have there own slider. If you want you can look at the code of my old site and see how it was done. I have had this same site rebuilt using this theme because there were issues. The old site had this feature Fix the woo commerce to be clean and correct... Take a look at the picture it has some errors that need to be fixed as well type 122222222222222222222222233333333 if you can do the job
