409985 Zen Cart - CanadaPost Shipping

We need two changes. One is for shipping window and the second one is for payment window. Shipping - We have the website currently with hundreds of items. It is NOT live yet. ALL items have been entered as lbs. It used to work fine with the Canada Post module until recently. It appears as though if we change those weights to kgs, then it works fine. If not, then we have issues/errors (see shipping PDF attachment). We have read up on the [login to view URL] forums. However at this point, its a pain to go back and convert all weights to kgs. We also use UPS to ship to U.S which uses lbs AND Canada Post to ship within Canada which uses kgs. What we want -- is an expert Zen Cart programmer who can make this work 'as-is'. There is some minor hard coding. When you are done, we want this site talking to Canada Post and to UPS and working flawlessly. Payment - Please see two attached PDFs. One is shipping window PDF and other is Payment window PDF. If you see the shipping window PDF, we programmed it such that the site-user can use the shipping courier of their choice by choosing that option and entering details below in the text area. We want to do the same with payment option. Some site users already have an account with us. So if you see the custom shipping option, we want you to do the same with custom payment option. Can you do it? This job is time sensitive. Again needless to say we want a Zen Cart expert who knows what he/she is doing. We do not want you going in there experimenting and/or breaking more things than you can fix. Give me a time (a realistic time frame) and how much will you charge? Please quote both parts separately. Shipping issue is more important than payment. Need to decide within 24 hours. Please do not waste our time with useless chat or data. Once approved, the money will be escrowed into your account and released ONLY upon satisfactory completion of then project.
