2 projects - Sort Order for products & Order conf. issue

PROJECT 1 - product sort order I would need an experienced oscommerce developer to create some modificaton which would let us to choose the sort order for the products within the categories. Of course here can be used some existing modification if there is one. Our shop is modified oscommerce shop. At the moment we can only choose the sort order for the categories. PROJECT 2 - order confirmation issue In addition our shop has a PROBLEM with the checkout process and this need to be fixed: The problem is with Paypal orders is sometimes created two duplicate orders which have 2 different order numbers. The orders have different statuses - another one is "pending" and another one is "Preparing (Paypal IPN)" This only happens if the customer goes trough the whole order process. So not every time. Also I would like to make sure that all customer will receive an order confirmation even if they would not go trough the whole process (but would of course pay). This does not happen now with our shop with Voice Pay payment method at all and sometimes if fails with Paypal also. Only if the customer pays trough the WHOLE order process and pay with paypal they will receive an order confirmation (2 of them with different numbers). At the moment we send the order confirmations manually on the shops admin section. Bigger projects available for an experienced developer.
