Three Customizations in OsCommerce

We use OsCommerce. We have three main projects we need completed in our OsCommerce store as follows: 1. We would like to add Accessories / Supplies section to our product pages that can be updated via the admin section. This section would be available to each product page and would show the following columns: 1. Product Code 2. Item Name & Description 3. Price 4. Qty 5. "Add to cart" Button (when they press the "Add to cart" button, the quantity they have input in the qty field of the accessory/quantity would go in their cart.) The user would be able to add not only the main product to their cart, but also any accessories and supplies that are listed for the product on this page (without leaving the page). 2. We need to add a "Click here for Instant Price Quote" to some product pages that pops up a window requesting: 1. First Name 2. Last Name 3. Company 4. Shipping Address 5. Shipping City, State, Zip in different fields 6. Phone 7. Fax number and 7. Email. The page should also reflect the product they are requesting a quote for (for confirmation purposes). A button to "Submit" and "Reset". We need to be able to set the "instant quotes" that are sent per product in a table in the admin section. When the "Submit" button is hit, it pulls these instant quotes from the table and emails the quote instantly to the email address the customer has input. We also need to be able to alter the template/verbiage of the email that is sent to the customer. We also need to automatically receive an email at a specific email address telling us that someone has requested an instant quote and include all of the information input by the customer in the email. 3. We also need a minor problem fixed in the OsCommerce, whereby the hyperlinks on the menu are different colors and sizes on some pages for some reason. We want these consistent. We think this was messed up when we added some hyperlinks in html code in some of the product descriptions. Somehow this affected the fonts, sizes and colors of hyperlinks in the menu.
