fix my wordpress website maintaining data and altering some areas

I have the current website [login to view URL] Hosted with justhost and with wordpress theme jobify jobify theme demo is here: [login to view URL] since update of theme my site is all broken in areas. i have previously had a developer alter the site to include google adwords inbetween job listings. i dont know if this has contribuited to the error or not, i dont think so. errors found so far which may helpo identify problem: (1) there was 2 different slider images at top of front page, they were located in same position as the demo site and spanned across the whole page left to right exactly like the demo. (2) position of all the company logos near bottom of the front page where on a slider with button to click left and right to expand / move through them. they are now all randomly placed in a mess. see demo site also (3) when you click on "jobs" page there was a map in the gap that is now empty space between header and the start of the jobs listings. this map previously displayed with locations of all jobs like on demo site (4) "cart" page shows [woocommerce_cart] code (5) "checkout" page just shows [woocommerce_checkout] (6) sign up page shows nothing (7) when you click on a job to open the job details the image size of clients logos is huge and inst correctly shown like the demo site (8) plans and pricing page is blank i would like to have the site fixed to be exactly the same as the demo whilst maintaining my own data and job adverts already on the site. i have of course altered fields to suit my data and industry which need to be kept but the actual positioning of images and functionality of woocommerce plugin don't seem to be working properly. i would also like to find a way for me to allow clients to upload mukltiple jobs at the same time by CSV upload. i need this because many clients have 100's of jobs and individually adding these will take too much time so they will not use my website. this is a feature i really would like to have here at my disposal if possible so csv file would create pultiple job listings automatically
