Hi, I'm a Delphi developer with more than 30 years of experience (yes, since the times of Borland's Turbo Pascal). I also have extensive experience with Firebird 2.0 and up. The past 20 years I was full time employed (in-situ) by two international organizations; the Inter-American Tropical Tuna Commission (San Diego, CA, USA) and the Food and Agriculture Organization of the United Nations (Victoria, Seychelles). I'm currently retired, and trying to stay busy doing some freelancing, so I have enough free time to dedicate to your project.
I'm sure I can help with your project, but you don't provide enough information to make you a realistic estimate of cost/time. My offer, then, is for 5 days of my full-time work on your project.
If you think you may be interested in my services, please send me a PM. This way we can discus the details of your project and I can share a copy of my CV (for you to check references/experience).
Best regards,
Marco Garcia
