From your project description, I can not estimate the time and price exactly, so the numbers I have entered are not for real.
I have more then 15 years of experience in Delphi programming with Interbase and Firebird databases.
I have been working with Delphi 2010 since it was released and with Firebird since version 1.
So I am very professional and experienced in the areas, you are looking for, so please let me know more specifically, what the project is all about.
After that I can give you a real offer.
Best Regards,
Ove Bjerregaard
