ask How much does it costs for a different appi? 
answer

We can customize an appi with logical cost if you find our application usefull.The cost depents of the changes. (We work on php/asp/asp.net and all known dbases & rdbms)

If you have your own database we can make a data-base managment  application for only 10Euro/table and 4Euro/field plus 80euros .  (For example  a dbase with  6  tables and  60  fields costs 380euros and includes add/edit/delete/smart searching/print/export to pdf/xls/doc etc)
