Complete Our App

Hi there,
We are looking for a developer who can complete our project - the "Custom City Map Editor"
for our customers.
We have some code and functionality from the previous developer, so we would like to
complete it.
What we have:
- WordPress and WooCommerce
- custom WordPress page with the Online editor
- custom plugin with some functionality
- 15 styles and 12 map layouts
- 20 sizes: portrait and landscape modes
How it should work:
- You create a personal city map via the Online editor
- You customize the map: style, wording, size, markers, orientation, etc.
- You add the map to the shopping cart (you can add multiple maps/designs/items to your
shopping cart)
- You make a payment and receive your personal map (maps) to your email
- The map should be created on a server as High-resolution files: JPG and PDF. The quality is no
less than 200-300 PPI. We have examples.
What we need now:
1. To make a few light changes in Design (3-5 changes), make it more friendly.
2. To finish the layout templates in both orientation modes: borders, text positions, font size for
all sizes. Now it is completed for 80-85%.
3. To add the custom size section. It was in the original design
4. Check and fix the custom plugin: to add the possibility for adding new styles, layouts (if
possible)
5. Check and fix the map saving process on the server.
6. Check the sending process to customers.
7. To make the possibility of adding multiple maps/items to a shopping cart.
8. Check the work in browsers and mobile
