Purolator Shipping Extension for OC4

Hello Everyone,

Not sure if this is the correct forum, so my apologies if it not.
We are currently developing an extension for a customer for Purolator Shipping using OC 4.0.2.x. The extension will allow for lookup of rates, create shipments and create documents (i.e. label, customs invoice, etc.). Development is almost complete (currently testing with Purolator). It will not modify any core files. Please let me know if there is any interest and we may offer it up for purchase.
Thank you.
