I need a custom product module created

I need a custom module needed.

High level overview:

I am creating a blind site, similiar to selectblinds.com. The user will enter
the site and select the blinds, add them to the cart, etc.

Each blind has the following variations:

3 types of blinds (Faux, Composite, Wood)
Each type has it's own set of colors
Mounting style - Internal and external
Height & width

The height and width is the tricky part. Each type of blind has it's own pricing
table, based on the width & height.

Here is a sample pricing breakdown for wood blinds:

Height Width Price
20 12 $20
20 14 $25
20 16 $25

If the user selects 20 X 12 1/8, the price would be $25. The blinds can be sized
in 1/8" increments, so if the user selects 20 X 12 5/8 the price would still be $25.
The price is a function of height & width.

We tried to implement this using the Drupal 4.72 Ecommerce modules (apparel module
with product variations applied).

Take a look at what I have so far at:
http://www.basicmagic.net/cashandcarryblinds/web/node/556

We came close, but there are a few issues we have'nt figured out how to solve,
including:

1. The price for each blind is NOT calculated based on the width & height. The
closest thing I found is pricing options in the product variations. Notice on the
page above that the price is displayed on the first page - but it should
not calculated

2. Once the blind is added tp the shopping cart, it must behave exactly as a normal
product would, meaning I should be able to log in as an admin and see the product
in my store, ready for shipment.

3. I do not need an admin interface created to manage the prices of the blind.
I can write a sql script that updates the database if the prices change.

------------

I would prefer to use existing modules if at all possible if you know how to fix the issues
I mentioned above.

Send me your relevant work history, sample urls and a bid. I need to get this started right away.

I prefer someone who has worked on previous product modules in the past.

Payment is 50% up front 50% upon completion via paypal.

email me with any questions- 'c.wilde at teckcrew.com'

thanks,
