Magento B2B website development

Hello. We are looking for a Magento developer to set up a basic B2B e-commerce website. Here are some of the requirements:

There might be additional Magento extensions to be installed and implemented. We expect the developer to propose the extensions to be licensed:

- Multi-language extensions
- An extension to insert multiple items
- A coupon extension
- A B2B extension

We don't need a custom theme. The developer should organize the main page and the rest of the pages using the professional theme that we choose.

There will be custom stores for five language groups. Same products will be sold in all of the stores but the price tags will be different. Data of sample products will be inserted to test the system.

We have an Ubuntu-flavored VPS. The developer should make any settings needed to improve the security and the speed of the server.

We do not expect any custom coding in this project. However, if you think that coding will be needed, please add coding as a service in your quotation.

(1) Please indicate the total hour expected to finish the project.

(2) The cost of your service.

(3) It is not necessary, but you could be so kind to mention the cost of the extensions you might use in this project.
