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 developing with indy. I can develop a fairly simple DHCP server on UDP port 67 (standard). If you think you may be interested in my services, please send me PM. I can provide a copy of my CV and we can further discuss your requirements.
best regards,
Marco García
