Getting single rates

I really need a class to retrieve rates from UPS. Have tried several scripts but none seem to be accurate. Too much of a n00bie to get this class functional.
Willing to make donation (or direct pay) for some assistance in getting a functional script.

Hello,

For Shipping Rates, check files:

src_readme.txt with a sample of usage:
you must read ups manual to know the set-up params like

Shipper (yours) credentials, From Address, To Address, Package type , Package weight, Package estimated price.

src_ups_rates.class.php is the core code but you dont need to look into in unless you are having unexpected behavior/result.

Hope it will help, donation is not an option for my location :)

If still unable to use, reply with some more specific issue details - i'll deal with it.
