Opencart vqmods for admin & product customization

1) Rearrange Checkout fields, check street adress & subtotal - your task would be to rearrange the checkout forms into a more logical order (see attached image) (this can be hardcoded) - If there isn't any number in adress1 field -> onecheckout the page must show error (this can be hardcoded) - Minimum order amount for cash on delivery: If order subtotal is < 1320 & customer select cash on delivery -> onecheckout page must show error (vqmod) 2) Add product thumbnails in admin-orders-view (same style as in admin-products list, see screenshot) (vqmod) 3) Add % discount to orders manually in admin - in admin - order edit possibility to add % discount to subtotal (vqmod) 4) Alternative product variable vqmod: (See screenshot attached) There are some original items pictures on my PC which differ only in image, but they are the same in price and description. I want to upload all the images to the store. I need a mod which does this: - In admin I should be able to mark alternative products, which can have variables (more product variables to one item) - I need possibility to upload more images to a product, and the store must "know" they belong to this item - store front should show only the actual image in queue and show stock only: 1 - after customer orders one from this item, store automatically changes the next alternative picture of product in queue, sets product quantity 1 again, and puts it onto homepage into "New items" section (edit time must be changed). - if customer buys product which has variables -> if product has alternative images in queue -> store changes to next image of product variable & sets qty back to 1 (product variables should always show qty:1 in store front, but number of items in queue in admin-items list). I need a menu where I can see if cron jobs are run without problem. - In admin-orders-view I need to see with thumbnails which variable items were sold actually and I need possibility to delete images of sold variable products to free up server space - If there are no new variety images left of product on server (just the old, sold ones) -> this has to act the same way as normal product on store front -> item is out of stock 5) Search for similar words (vqmod) - many customers mistype words, the product search must show products with similar words Please write in your proposal in brief, how would you make the website recognize if a product variable was sold (so it can change to next image in queue). Tasks 1-4 are important, if you don't do task 5, its OK, just write in your proposal. Please don't search me outside freelancer with your proposals or services.
