Hi there,
This sounds quite do-able - provided your specs are concise and complete ofcourse! I've been developing Delphi apps for about 10 years now, since Delphi 2 and now 7 and 2006. I've got vast experience in other languages and tools including VB, Java, PHP, numerous databases and more.
I run a micro-ISV and we have vast experience developing and implementing business apps for stockbrokers, mobile network operators, estate agents and more.
This is the stuff live, eat and breathe - Delphi. I hope you find my price agreeable and look forward to working with you.
All the best, I sincerely hope you meet your target - and hope I can be of some help!
