Integrating code for GLS shipping

Hi
I am using opencart 1.5.1.3 and i want to use GLS as the carrier of my products.

I got different codes and intructions from GLS. but i don't know what to do with it or where where to place the code.

I want to use GetParcelShopsInZipcode. the code for that can be found here: http://www.gls.dk/webservices/wsPakkesh ... sInZipcode

I also recived further guidelines and documentation. you find them attached.

is this a job for you then please contact me - also to let me know your price.

hope to hear from you:-)
