WORDPRESS CUSTOMISATION / DEVELOPER

WORDPRESS CUSTOMISATION *** Wordpress developer & customisation *** We built our site but we are strangling with some customisation/ script. Part I - There are minor adjustments to be made as we are not professional developers. (update plugins without loose content, break an image on homepage to be responsive with the text, make it all work correct on ssl, add an image to a custom calculator, make a calculator image to be responsive as well the forms & copy of the calculator function to home page). Please note that the special calculator is ready, it was custom made for our website needs. But if you can make it looks better and more modern, like a touch up, We would appreciate. Part II - development/ customisation for 'my account' which is the heart of this project - It is a website created for a shipping routine, so it need to be a little different than standard and maybe be linked to a admin control like woo commerce for example or create a new one; and this area can only be displayed when a user log in. Let me detail it better. *** There must be 3 columns: On the first, links to 2 tables (forms), but items from tables must appear under tittle. When these items are received, we need to have an option to update and they auto goes to the second column. User receive auto notification. So the user can choose to dispatch one or all items and pay for it, so payment integration must to be part of it. Once its paid, we need to have an option to update as dispatched (user receive a notification), so it auto goes to the 3rd column where we would be able to add a tracking number, making the user able to track at any time as well see old orders. All this columns must be linked to some admin functions as we need to control it as explained. We are always open to suggestions. We don't mind if you will use a plugin, pre made script, or make from scratch, as soon as the website is finished, attending to our needs, We will be happy. What's your best price and time scale please? Many thanks
