Hellou.
Im not sure why u r posting two same offers but either way ... Im osCommerce programmer with 10 years of practice. During that time i was osc forum admin and co-developer of 1st polish B2B version.
I was doing wide sort of mods strating from simple instalation, extenstion, creation of new one, integrations with external suppliers and couriers.
If you know what you need just tell me and we gonna do it fast, swift and keeping osCommerce standards.
Best regards,
Trygon eXtreme
