Invoice Tracking - webprogramming (php, mysql) pdfexport, advanced tablehandling, simple webservice integration, simple login

Hi, For this project a webpage has to be programmed using php and mysql. The site is used to track invoices. A website (without functionality) has been created to show the layout and understand the functionality. [login to view URL] Additionally description is provided here: Overview: [login to view URL] [login to view URL] Invoice add: [login to view URL] [login to view URL] Begünstigter add: [login to view URL] [login to view URL] Patient add: [login to view URL] [login to view URL] Bezahlen: [login to view URL] [login to view URL] Abgeschlossene Rechnungen Detail: [login to view URL] [login to view URL] Abgeschlossene Rechnung: [login to view URL] [login to view URL] Print KK: [login to view URL] [login to view URL] Print Beihilfe: [login to view URL] [login to view URL] An MS Access DB exists which shows the functionality, which I will send when requested. Features that are needed, which have to be programmed: 1) Simple user Login, but also pages have to be secured and cannot be accessed with that logged in user (webpage in similar layout needs to be developed) 2) adjusting existing (above) css and html to a readable format 3) programming tables and entry forms (dropdowns, datepicker, etc.) and advanced table handling (see above) 4) exporting to pdf with grouping (sum of db items, which fullfill certain criterias) 5) generate IBAN and BIC numbers with simple existing webservice integration 6) Bezahlcode integration simple existing webservice integration Code must be readable and well documented. If you have questions please ask. Greetings Hannes
