Build an Online Store with many parameters to use extended search features -- 2

Main function of the new Website will be focused on Online store (e-commerce). Whole project consists of : 80-90% similar design, solution and features as it is now on [login to view URL] + the new features : NEW features are : - synchronization of products data with MsSQL DB, which is located on local company Intranet server (due to application for stock management) Main emphasis are for synchronization of product parameters (width, height, colour, power, surface, etc...) a creation of advanced search filter will be a must. The new website (parameters search) will be very similar (in terms of fucntionality ) to this one (multiple selection with this or sliders......): [login to view URL] or [login to view URL] The system must be powerfull enought to work with great amount of datas : 10 000+ products, each product will have about 10 parameters, some even 20+, so the load of informations will be huge....efficient database queries required Second important part of this project will be a layout of the products view. This e-commerce will be in "Catalogue view and export", from which we will be able to print to PDF : 1. any product details similar as : [login to view URL] 2. whole category : [login to view URL] 3. whole selection of categories (or whole eshop) as here (needs to wait several minutes - there is many products ) : [login to view URL] Recent solution is basicaly how the new eshop should look like(except the search filter is not there), but the database in recent eshop is not synchronized and the Joomla is too old and not powerfull enough to take the full load what we need. This project is for : 1, installation of the core of the e-shop. 2, create function to synchronize the informations MySQL/MsSQL 3, create function to synchronize the datasheets, pictures etc. saved on local intranet server to our web hosting provider web-folders 4, the product listing will be similar to our existing listings (as in our recent e-shop, ) ..some minor changes in design due to support for mobile devices will be accepted 5, create a advanced search filter bar as found on Mouser website, so the products will be easier to filter. 6, create function to print to PDF a displayed products listing (product details, category, etc)....for e-catalog use.(similar as now) 7. create 80-90percent of existing features and functions on new platform, the rest will be discussed... 8. move existing eshop data(structure/menu, users, passwords, articles, products, URLs,...) completely to the new system 9. some minor changes in regard to design upgrade, etc will be needed as we work together on it. 10. After work finished, complex report and data structure, project description, features way of work will be delivered for future upgrade. 11. most of the modules/gadgets/features will be focused on to work with / load data from google products (photo gallery - will be connected to picasa, video-youtube,etc....) 12. existing user informations/passwords has to be transfered in such way, that it will work on new system without user interaction(so they dont have to change and renew the passwords..) 13. URLs : all main static URLs has to be kept the same (menu, articles, newsletters) for products we can accept some 301 redirects solution... Existing web important functions : multiple languages, newsletter system, eshop product listing as it is now, contact form, print-to-pdf with catalogue-like page break, eshop funcrions ... ....more features needed will be solved and posted as different project.
