Shed Doors

After A Windstorm Here In The Northeast, My Backyard Shed Doors Blew Right Off! They Are Bent And Unusable. I've Looked Online But Can't Find Anyplace That Sells Such A Thing. I Don't Want To Pay For A Whole New Shed. If I Could Spend A $100 Or Less For 2 New Metal Doors I'd Be Happy. Any Suggestions?
The Shed Was Here When We Bought The House A Few Years Ago. It Appears To Be More Then 20 Years Old So Determining Who Made It Will Not Be Possible.
