Need Modification made to my website, some tweaking.

I recently purchased this whole script: [login to view URL] And need two modifications made to it, do not bid without messaging me for MY URL to my website so you can view all the code. I'll be giving the winning bidder ftp to my website, and admin controls to take over everything on their end. The paragraph below in the (****) is what knowledge is required, I HAVE THE FULL APPLICATION. Just need some modifications made to what I currently have! ***************To customize the colors and design of the application you will need to use HTML, LESS and CSS. To customize the designer tool you will need to use AngularJS with gulp To customize the admin you will need to use PHP The web application uses a simple REST api to communicate with the server. This is written in PHP. You may modify this to integrate it with your own shopping cart.************ ____________________________ First Modification: When you go to the website above (my website is the exact same, I bought the full source code from codecanyon, mesage me for my website), when you click on Image>upload image>and proceed to upload any imagefile,>start upload. The image goes straight to the product (tshirt). The modification that I'll like is it to add a another window like what they have at: [login to view URL] ^Were as when you click upload image>click here to upload>and proceed to upload any imagefile>!THIS SCREEN! (Select ink colors) The "select ink colors screen" on [login to view URL] is the modification i'll like on MY website since I don't have this feature. I'll like it exactly the same where you choose as many ink colors you need (more than one colors can be picked), then when you click "add to design", it will then proceed to put the image on the product (tshirt). Second Modification: By now your viewing all my code, and have admin rights to my website to change a few things. and ftp access to change files on the fly. With the above work done (select ink color screen), I want each ink color on that page to represent a price, this part is pretty much done in two ways, if you use my designer and add a text, each added text color will then add ink color to the shopping cart. Bridge these two so if the user select black, it will trigger the same thing so it works in the cart aswell. Third Modification: On the admin page, under PRICING, I can change the price per ink color. What happens is if I choose a product and it has one ink color, it will take the number set for 1 color and add it to the product cost. I don't want that structure. I want it so 1 color = $20, 2 color = $40, 3 color = $60, ect. When the user only has a 1 color ink job, 5 products. It will take the "product price" X "the amount of products in (s,m,l,xl..) = 5" + "add the ink color price: 20" = total price. Forth Modification: I don't know if the third modification should be after this or before, it's pretty much the same thing. When your on the admin section of my designer, and select inventory, you'll notice that ever product has a set price. Now go back to the designer>buy now page. You'll notice that it has that product price per item listed. Ex: Men's t-shirt says "$[login to view URL] per item" I want it so if the S, M, L, XL, XXL, 3XL select boxes equal a certain amount, it will add "UPCHARGE" to the product price. (upchage list below) EX: If you select between 5 total sizes ( 3Small, and 2 XL) then it will add a $9.35 upcharge to the product price. If the user puts in 27 total sizes, then it will add $3.40 to the product price, ect. The chart below represents what I'll like to have added to the quantity amount in each number. 1-6 $9.35 7-12 $6.35 13-18 $3.60 19-24 $3.50 25-30 $3.40 31-36 $3.35 37-42 $3.30 43-50 $3.25 51-75 $3.20 76-100 $3.15 101-125 $3.10 126-150 $3.05 151-175 $2.85 176-200 $2.40 200-250 $2.30 251-300 $2.25 301-400 $2.20 401-500 $2.10 500+ $2.00
