Build me a new Item Add Wizard

We are looking for a developer to build a custom item add wizard for HQ Manager. Specs are:

One screen that shows entry form for:

1. Item Lookup Code
2. Description
3. Price
4. Cost
5. Margin% (it shows the % when Price and Cost are entered)
6. Quantity boxes for each store. (We have 3 stores. - This is different from others in that we enter qty at HQ before updating each stores. - We do not use PO or item receive check) Should be prefilled with 0.
7. Deptartment (dropdown)
8. Category (depends on which dept selected) (dropdown)
9. Supplier (DROPDOWN)
10. Barcode (dropdown with preselect of Code 128A)
11. Tax is always preselected as taxable.
12. Add and Cancel Buttons Item type is always Standard. (This is not shown in the wizard.)

When you press Add, it checks for duplicate Item Lookup Code and if it is duplicated, it shows an error message (not in an popup but above the item lookup code box on the wizard) and the curser goes to the end of Item Lookup Code.

If you are interested, please send me a quote. Thanks!!
