OSCMax 2.5.4 Order Total Modules (2 of them)

Need two new "order total" modules for a oscmax 2.5.4 store where the store puts up their cost of products and that's what goes into the cart. When the order total is shown it then displays their "margin" which is added to the order. In addition they want another module that totals the entire "order total" and then adds another charge line for CC Processing before the Total.. 1) Our Order Margin Order Total Module Takes the Order and adds a line to the order under the subtotal that has gone through the order and used a margin that was in the Admin to multiply the order by. So, an order where the products added up to $100 where the margin in the admin was 20% would add a line to the order that would be: Our store margin is 20%: $20.00 2) CC Processing Fee Order Total Module Much like the above, this computes all the order total items (order subtotal, margin, shipping, low order fee, etc.) that have come before the CC Processing fee and then applies the multiplier entered in the admin (ex: 1.9% + $0.20) to the order total creating a new order total line: Our Credit Card Processing Cost: $2.13 ---- Why? The store is using a cost+ model where everything is broken out in the order totals in the shopping cart and checkout modules. The user sees and adds items to the cart from the store at the listed cost for the store. Then at the end of the order the user is presented with the cost for the store owner, the owners margin, shipping cost, tax, low order fee, any discounts they may include and then the cost for processing the credit card. The result is the grand total for the order. This way the user knows the exact cost of everything that they are paying for, as well as exactly what the store owner is making on the order. The store owner is referring to this as "his costco model" where everything is 100% transparent to the customer and all his sales are at a flat margin for him. The software will be run in the current version of oscmax's one page checkout.
