365789 Magento Store Credit Module

**Store Credit -- from community extension reward points** version: Version 0.2.3 - Tue, September 22, 2009 currently it's updated to Version 0.2.9 - Wed, October 14, 2009 [login to view URL] Specific expertise that I am seeking: You should have experience programming Magento Commerce websites. Experience with MySQL database programming and Rackspace server hosting is an added plus. Timeframe for delivery: I need to have this up and running within 1 week. Issue we need help with: The reward points system are created based on coupon system, which works in a way that doesn't have any observers to update the coupon value in shopping cart and checkout page. Because of this, here are several issues come with it: [login to view URL] credit points won't be adjusted in the following situation: a. customer don't do estimate shipping and tax in shopping cart, the maximum store credit that can be applied is subtotal, in this way, customer would have to pay for shipping and tax in checkout. b. customer do estimate shipping and tax in shopping cart, the maximum store credit would be the amount of grandtoal. [login to view URL] use the same address to checkout as shipping address, store credit covers their whole order. which means it works as return properly. [login to view URL] changes the address when they checkout, the store credit applied to the cart is still the estimated one, so if the new address has lower shipping+tax amount, customer would have a $0 order, but he/she looses credit during this order checkout. 2. The order invoice is not correctly calculated. the maximum Discount value from store credit in invoice would be subtotal which should be grandtotal value. so even customer applied the grandtoal value to the cart in frontend, the invoice still calculates as subtotal value. This happens in PDF and backend order management page.
