470 Expand Shipping option

I want to expand my shipping options to include as below for my retail jewelry site. This mirrors www.plumislandsilver.com. UNITED PARCEL SERVICE (UPS) All UPS services have guaranteed delivery times. Check transit times to your area at [login to view URL] (we ship from zip code 01985). These charges are approximate for a 1 lb. package under $100. Ground (1-6 days) ~$7.00 click here for UPS Ground transit times 3 Day Select (3 days) ~$9.00 2nd Day Air (Blue Label - 2 days) ~$12.00 Next Day Air (Red Label - 1 day) ~$30.00 (shipping charges can vary widely) UNITED STATES POSTAL SERVICE First Class Mail (1-6 days) (1 lb. max, $200 max order) This is a fixed rate schedule for First Class Mail only. This rate does not apply to any orders that include catalogs or display items. Order Size Shipping Charge $00.00 - $25.00 $2.30 $25.01 - $50.00 $2.85 $50.01 - $75.00 $3.40 $75.01 - $100.00 $3.95 $100.01 - $200.00 $5.50 Priority Mail (2-3 days - not guaranteed) ~$8.00 (approximation) Express Mail (1-2 days) ~$25.00 (approximation) I currently offer free shipping 1st class USPS for US/CA orders over $30. However, if someone else outside US/CA ordered -- in truth, the shopping cart would probably give them free shipping if they met the dollar amount. I want that corrected.
