Build a Custom text on a product feature for E-commerce Magento

I would like to make a functionality according to this link- [login to view URL] Functionalities in detail: I have magento 1.9 at the moment. In the link I sent you, the features present are the following- 1. Pre defined fonts- selected by admin for that Glitter case in backend. Admin should have an option on SKU level which font a customer should be able to use. If admin has 10 fonts stores but wants customer to use only 4, admin should be able to select from backend and customer will use that. 2. Font alignment - portrait and landscape mode. Please note that an area was selected in backend by admin to allow customer to write the text only in that area. Incase, the letters were increasing, font size reduced. The area is selected for portrait mode and landscape mode. 3. Color of font- color of font can be changed based on what an admin wants to show to customer. It's upto admin to decide which colors to be shown. 4. Mobile responsive as per the link- I feel this isn't a tough task. The mobile version in the link I sent is fairly simple and can be done. Our mobile traffic is 85%. 5. Live font apply- as and when a user is writing, fonts are appearing on the product. User doesn't have to click on apply button. This is an important feature. 6. Font can be edited in the text box and on the product too. - This is not required. But you can let me know if this is something which can be done easily. 7. Please open this link- [login to view URL] In products like this. Customer has an option to customise 2 parts of product Individually. Both the 2 places can have either 2 different font style, 1 numeric and 1 albhabets, Or both numerics. Hope this helps! PFA some pictures. Additional info which can be used only If it helps- My website is currently using a plugin which is open source and which uses VML (Vector Markup Language) and SVG (Scalable Vector Graphics) to upload images on products which can be customised as per customers need.
