custom shipping module

I need to create a completely custom shipping module for Zen Cart. It takes into consideration product quantity, dimensions, weight, post code and a few more factors. I have an Excel file which is used to calculate the cost, no additional documentation. I'm looking for someone who can build this module rather fast. You need to know Zen Cart, I don't need people who will try to learn in while working on this project. I'm looking for a long term co-operation since I have a lot of work and would like to share it with someone who's good at Zen Cart. You must speak FLUENT English! I prefer individuals, not companies and project managers since I want to be in direct contact with the person working on my project. Please reply with the term "Time is Money" so I know you read my project description. Otherwise your bid will be ignored. All interesting applicants will receive the Excel file to review it. Please make a placeholder bid - I understand that you can't know what it takes for this project until you review the file. You can always edit your bid amount later.
