Modifiable Reports Program written in Delphi

I have a third party firebird database which has an existing reports module. There are some new? reports which I think would be beneficial to my system and to me. I need a reports program which the programmer will have to populate with requested reports and which will allow me to add any number of custom reports myself once I get familiar with delphi which I am currently learning. The database is firebird and once programmer has been selected I will forward on a copy which has some data in it. The programmer should treat the database with great sensitivity ans assure me it will not be used for their own progression.
