Customer D6 Ubercart shipping module

Hi, We are looking for a Drupal 6 developer to design a custom shipping module for ubercart which will consist of the following 3 shipping options: Pallet B: Will be equal to or less than 2 X SINGLE item types (specified in taxonomy/uc catalog) with a flat rate of £70. Pallet C: Will be >= 2 * Single item type or >= 1 * Double item type (specified in taxonomy/uc catalog) and will have price multiples depending on weight criteria i.e. <= 1250kgs = £85, <= 2500kgs = £170, <=3750kgs = £255 etc. Post: Will be any accessories which fall outside the above criteria. The other problem that we have is that we need the module to change the price depending on which postcode region the customer falls within. We would need to take both the postcode prefix and the first set of numbers to determine this info. i.e. CF31 might be £85 whereas CF37 might be £100. We will give the winning bidder all this necessary information. I do have a link to a similar module if this helps. Please ask any questions if you are unsure of anything!
