Help to modify Products/Cataloger

[Psykis]

Hello,

I need a product catalog which includes certain features but it seems that I can't do this with Products or Cataloger modules. Can you make some kind of modification for either of these modules or suggest a better module?

Product catalog should has 4 different levels:

PRODUCTS -page is a simple page with text and list of level 1 categories.

LEVEL 1 CATEGORIES: These category-pages have text and list of level 2 categories.

LEVEL 2 CATEGORIES: These category-pages have text and list of products.

PRODUCTS: There's no need for detail pages. Products should be listed in level 2 category-pages, but they also need to be edited separately and placed to more than one level 2 category-pages.

My difficulties with Products and Cataloger -modules:

Cataloger: I don't know how to list detail-page -content in one level 2 category-page and Content Aliases -module isn't working with CMSMS 1.8.2

Products: I don't know how to list detail-page -content in one level 2 category-page and there isn't possibility to make sub categories.

Anyone willing to help? I can pay if you could solve my situation.
