Hi,
Even though you're requiring presencial collaboration, I'd like to offer you my AS/400 programming services, as I've done a whole career around this platform: System config, application programming, RPG/ILE, COBOL, CL, DB2 Database design and admin.
Once you're done with the system set up, you might want to hire a top quality programmer for remote development.
I'd be most pleased in holding further talks with you.
Thank you,
Grunty.
