ODOO 10 Customization

We are using Odoo Version 10 and we need more customized fuctions and system interface for our company, hopefully you can help us to develop 4 plugins. Please reply us your opinions, as well as the quotation for developing the following customized modules: Plugin 1: Delete all the columns relating to tax and correct all the wording properly (e.g., Price before/after tax in a quotation, these names is not appropriate in our regions). Set the default currency to MOP (create other 2 types of currency: HKD and CNY) Plugin 2: In the Sales Module: Page: Sales > Customer [list format] - Show all the column as in the attached file (Template - Customer Record). - Set the default format as list format, rather than Kanban format Page: Sales > Products - Set the default format as list format, rather than Kanban format - While creating new products: 1). Cancel automatically clicking "Can be Purchased"; 2). Change the Product Type as "Service". - While a product contains too many product attributes [FYI: attachment_1 and attachment_2], can we set the new product efficiently? (e.g., Can we set a new product with a interface like the page of a customer using eShop, an example page for reference: [login to view URL] ) Plugin 3: Quotation - Set the default prefix of the quotation ID as "PRO-". - Reset the quotation template (We can send the template to you if you insterested). Not required to match the template exactly the same. And we should able to add/edit the term and condition in the admin platform. Plugin 4: In the eCommerce Module: - In a specific product page (e.g., [login to view URL]): 1). Add checkbox function (the admin can add the checkbox option in the admin platform) 2). Add textbox function (the admin can add the checkbox option in the admin platform) 3). Add upload file function (limited to some specific file type, e.g., jpg, doc, pdf, ai) 4). Delete the default action of replying an email with a quotation after making an eShop order by the protential customer, and delete the "odoo" logo in the email template. We want to verify the quotation automatically created by the system first. - The customer can sign the quotation electronically.
