customize OS commerce

1A: In the admin section of oscommerce, when I am in a category & see the list of different products they are sorted by alphabet on product_name. I want them to sort by product_code. (NN01, NN02 etc) 1B: I also want this page to display prices in the list. At the moment it only shows "Categories / Products, Status, Sort Order & Action." 2: I need some help with the Placement & css formating of the category description text. At the moment if a visit a category with a product in, like [login to view URL] the cat desc text is placed above the Category Title, where it says 'Funky, Funny, Fluro, Fractal . . ' on top of 'DOLLS', but it should be DOLLS on Top instead. Also the description text size is too [login to view URL] should be the same size as the description text on this page, [login to view URL], which has no products in it, only other categories. 3 : I want to install some kind of gift voucher contribution to the webshop, (where a customer can buy a gift voucher of say ?'?100 as a gift for his friend.) Do you know of any good contributions and would you like to install them for me, so they fit with the look & feel of the present site ? 4 Our ImageBank admin (Gallery 1.5 contribution : [login to view URL]) is not working properly. I am unable to upload new pix, or edit the titles for pictures that are already there. I get these errors "Error: Unable to make thumbnail (0) Error: Could not open lock file (/var/www/vhosts/[login to view URL])!" and "Error: Could not open lock file (/var/www/vhosts/[login to view URL])!" So I want to install gallery 2 (so it looks & feels about the same as our present version) or maybe it is better to do a quick fix to the present version ? ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
