"Hot Folder to FTP" script review please

Question

I'm trying to make a folder on my Mac that is a "Hot Folder." I want this folder to have an action/script that as soon as it sees a new file added it will open Fetch and upload via mirror to an FTP folder.
I was able to make the Fetch portion of the script without issue, but making the folder "Hot" is a bit more difficult for me. I tried to use some script from the sample script "add - new item alert" but have been unsuccessful. I'm hoping some of you Applescript pros can review this and tell me how to correct. Or perhaps you know of a better way to make this work with automator.
SCRIPT:
on adding folder items to this_folder after receiving added_items
try
tell application "Finder"
--get the name of the folder
set the folder_name to the name of this_folder
end tell
-- find out how many new items have been placed in the folder
set the item_count to the number of items in the added_items
--create the alert string
if the item_count is greater than 1 then
tell application "Fetch"
activate
make new transfer window at beginning with properties {hostname:"ftp.hostname.here", username:"myusername", password:"mypassword", initial folder:"/pub/pao/images/"}
mirror alias "Macintosh HD:Users:Bill:Desktop:test:" to url "ftp://myusername:@ftp.hostname.here/pub/pao/images/" format Automatic without delete strays
end tell
end if
end try
end adding folder items to
Thank you all!

Well, the most obvious problem is:
if the item_count is greater than 1 then
If you drop a single file into the folder, nothing will happen. That's because item_count will be 1, not greater than 1.
If you don't care about how many files were dropped (because Transmit's mirror function will just synchronize the differences, then omit this line altogether - the script won't fire unless at least one file was added.
