Shipvaule Module Question/Help

[Sheld]

Hello,
I am currently using shipvalue in VirtueMart. I like being able to base shipping on the price of my items. I want to be able to add additional shipping options. Is there another module out there or how would I re-write shipvalue to give me these options.

For example: Standard USPS(5-7 Business Days) $8.90 (which I am able to do)

Want to add: Standard Plus UPS(3-5 Business Days)$13.80
            2 Day Express UPS $25.80

Thanks
