Custom Programming to WordPress Plug Ins

1)I have a woocommerce plug in along with a square POS plug in installed on my wordpress site. When I sell an item inside my brick and mortar store (no online sales), I need square to communicate with woo commerce to adjust the quantity of the item from 1 to 0 (out of stock) so that the item does not show in stock on my website anymore. 2) I also have woo commerce to facebook shop plug in, and it required custom coding to get the pictures to sync over to facebook shop. the very first picture in some of the items on the facebook shop are incorrect. the remaining pictures are correct, but the very first one is incorrect. I need this fixed. 3) Also, when you click on the item in the facebook shop, it has a button that says "view on website" but when you click, it takes you to a checkout page on my website as if you are buying the item, but I do not want customers to be able to do this. I do want them to be able to click to view the item on my site, but not go to the checkout page. 4) I have a craigs list to woo commerce product integrator. It takes items i posted on craigs list for sale and turns them into products on my woocommerce website. I need this plug in to set a quantity of 1 for the item when it adds the item to my website. I NEED THIS WORK COMPLETED RIGHT NOW. I WANT TO WORK SIDE BY SIDE WITH YOU AND HAVE YOU FIX THESE ISSUES NOW. NOT TOMORROW. ALSO, THIS REQUIRES CUSTOM PROGRAMMING, YOU WILL NEED TO KNOW HOW TO DO CUSTOM PROGRAMMING TO THE PLUG INS TO RESOLVE THESE ISSUES.
