Javascript, Php, MySQL, html calculation page

PROJECT of priceoffer-list online, with or without calculation functions. Javascript, Php, MySQL, html calculation page (mastership of eventOnChange and OnKeyUp is a plus) Three category levels : 1= the organisator, 2 = the participant supplier, 3= the customer/ buyer 1= The organisator admin panel= 1.1 Entry webpage with view on a pricelist, and a link to application form for suppliers, and a login for subscribed participant,  + a link to the entry of his admin panel. 1.2 is the supplier's application form. 1.3 is a read-accept-modify-or delete control page of the 1.2 forms Database for 1= all application forms with all details as Email, log-in = DB named DBorg The entry webpage is a simple html document OOo writer (see 1.1) 2= Supplier .with his 2.1 entry page similar as 1.1 but with copy of supplier's own productslist. And the link for log-in + control of his (3) customers (see category3) Also his link to the admin panel and to his customers/buyers 2.2 application form (same as above 1.2) He has also his 2.3 read-accept-modify or delete control possibility (same as above 1.3) Database for 2= DB1=application forms with all details as Email, log-in- (same as above DBorg) DB2= database for insertion of all possible productlines with reference and sizes. Here the supplier can enter 100, 200 or more productlines, the objective is to select the products he want to put in his creation of the pricelist of the day. Now he create his daypricelist 3.1 (probably 10 to 50 lines) with copy/paste of DB2 lines, and save it in his project-folder3, After a certain time he shall become 10 to 20 typical pricelists for rapid choice in this project-folder3 By this way he can also create pricelists for different kind of customers (great,middle or little) and different catagories of products, for target promotion. Next step of supplier = he re-open his daypricelist 3.1 and add against the reference, the product description and the size cells, THE PRICE per product. We call it priceOFFERS4 and this go also to an archive offersfolder4 ( 4.1 and then 4.2 and also .more for targets) DB3= database with names of customers by categories as for example: (Dbg=great, DBM=middle or DBl= little) or DB3fr=fresh or DBfro=frozen products or al other possible subcategories. Last action of supplier= he bind a customer category on his pricelist and send it out to the selected customers as a kind of ''pricelist place to the disposal of the customer, if he open it for view''.   If a customer has not open soonly his pricelist, and if a new pricelist is send in the meantime, only the last one shall be visible. A new pricelist crash the old. 3= the customer/buyer/client enter in the supplier's entry page, fill-in his application form and open ''his'' pricelist-page 3.1 (same as above OFFERS4). We write ''HIS pricelist'' since (due on his login) the supplier has insert his name and principal coordinates, at the right above the pricelist. This means that the supplier send out his pricelists to his customers, (or he bring it to the disposition of each customer) with the automatic obligation to insert some client's identification details + date and hour, at the moment that each specific customer open his personal pricelist page. (This is a partial include of client's inscription form) The first action of the customer, after he has open his pricelist, is the include of quantities at the desired productlines, and to save his pricelist-orderlist on his computer. This html orderlistpage is then send by Email to the supplier, who send back by Email, the same orderlist as an order confirmation, An other surplus development is possible: the automatic price calculation per line + total amount at page bottom But the provider has to mention this eventual extension with a separate cost and delivery time, Skype contact and milestone is possible,
