$30 - $250

Project Description:
We are trying to have our website ready with OSCommerce but we need a person who can fix a problem with the shipping calculator:
Our problem is that we need to have a system which allows dimensional weight for some items together with the classic system of only weight or need to know how I can solve this. For example:

Item A: 10 lbs, 15x15x15", UPS Price: $10.18, Our Price: $10.18 --- CORRECT
Item B: 10 lbs, 30x15x15", UPS Price: $22.05, Our Price: $10.18 --- WRONG due to dimensions.
Item C: 20 lbs, 15x15x15", UPS Price: $15.24, Our Price: $15.24 --- CORRECT
Item D: 20 lbs, 30x15x15", UPS Price: $22.05, Our Price: $15.24 --- WRONG due to dimensions.

The weights are being sent properly, and our shipments that aren’t computed using dimensional weights are priced perfectly to the penny.

However, we don't want to lose money on large shipments as our customers are being charged far less than our actual cost to ship on ‘Dim Weight’ shipments. This is costing us time, money, and sales. I tried to increase the weight of the item to compensate the box and works fine for one item but when the customer adds the quantity items to 2 or 3, the total weight goes too high and the shipping cost is exagerated.

If the solution offered fixes our problem, we have some other jobs that we can give to the winner and maybe we can work with him as webmaster. If you speak spanish is better but not mandatory. Please we don't want to "try". We need the person who knows about this. Please send links to see a sample. thanks!
