Shopify website revamp

Job ID: 32427908

Budget: $12,000 – $24,000 HKD

We are a Hong Kong based photo frame company.
We would like to add new function at our shopify website.
1. Mock up preview
We want to let our client to have a mock up preview at our website, for example 3 layer. First, let client choose background photo that we provide. (Bed room, meeting room, exhibition, etc.) Second, choose different type and size of photo Frame. Third, upload their own photo. So that client can generate their own preview. The best situation is to let client to save their data/result to their account.
2. Stock management.
We can custom make different size of photo frame, but the Shopify can only provide small medium larger for customer. We want to let our client to select different width and height of photo frame from 15-60inches. Beside, the wood use for the frame usually come in 120 inches, we want to build a system to calculate whether our stock have enough left to fulfill client's want or not. Say like we have left a roll of wood in 120 inches left, when client want to make 30*40 frame, total it needs 140 inches, so it should so out of stock.
