This is pretty simple, so if you bid high, you're just wasting your time – and my time. It would be just like the Catalog > Manage Products, with a few differences. You will be adding Catalog > Manage Clearance. On that page, it will list all products, and their custom options. So for example you have a product, and it has a custom option with three options. Then it would list the product three times. All editing will be done on this page - NO sub-pages are needed. See attached image for the idea.
