We are looking to developer an online photo-book editor like :
The user would be able to create photo-books with around 50 pages. The editor should be able to have functionalities like template, where user can select template and replace images and text, can images, update text styles, rotate, skew and scale images and text. change font, add stickers, position assets, export it as PDF and can print it in 300 DPI.
Please provide me with cost and time estimate and technology you will be using to build it. The editor need to be super smooth and memory efficient.
