Change script that downloads stock from external source and add to our system (php)

Change script that downloads stock from external source and add to our system (php). In short: We have searchmachineX and we have an API. We get stocks from local ERP system, but ALSO from 1 external supplier. We now get this stock by phph code that logs in to their website and 'scrapes the stock data'. We no longer need it to use this scrape script because this supplier now has a simple CSV file with item number and stock (2 colomns). So it becomes easier but we need our scripts changed to use this csv file which is on their FTP. More details: "SearchmachineX" is something we use internally online, it is a php page (access IP restricted) and this shows us product and stock info in an easy way without having to use a heavy website. It is a page/phpcode made by someone here long time ago. The API does pretty much the same thing but it is for external use for our business customers. Basically we want a part changed where some stock info is now taken from an online web interface and in the future we have to take it from an CSV file (more easy). So now it is more complicated and it should become easier code  This searchmachineX script works perfectly, NO CHANGES NEEDED, but there is 1 thing broken: Inside this searchmachineX script we have a connection made to 1 of our supplier, called ‘xxx’. This supplier had a website with a dealerarea where we could manually check stocks. Our script did search that stocks automatically. Task: I want the scripts to use the NEW csv file and you have to make the code to do so. Extra task: Also I don’t want to depend on that ftp, so I need that csv file COPIED from that ftp to OUR FTP every half hour. Other coder offered to do for 44 usd, but had no time now, looking for EXPERIENCED coder here that not only can do coding but also understand what we are trying to do here, so communication can be easy. Please bid below 100.
