Project Description:
We need to migrate our ecommerce store from Magento 1.3.1 to CE, we need a magento expert to fix all template issues and upgrade a payment extension.
There is another extension which is not compatible with 1.4: http://www.aitoc.com/en/magentomods_percent_tiered_pricing.html

So we will get rid of it and add a button somewhere in the backend to let the cron process recalculate tier pricing for all products that have an attribute (i.e. "percent_discount") set to "yes".
