We have a customer who has 50k products in their zencart shop. Unfortunately trying to use the google base module doesnt generate the file correctly. Only 1200 products appear in the file.
We suspect that as most items dont have a description, that is the reason of failure.
We do have a google base module modified for this, but does not work. (it copies the product name to the description field).
So we are looking for someone to either fix this module or create a new module.
Please contact me with your cost, timescale etc. PHP/Mysql required.
