How do I write a ksh script that will check if all ftp files are received?

I am trying to code a ksh script that will check to see if all 26 incoming ftp files have been received before proceeding to the next function, which is to rename each file.

Here is the pseudo-code of what I am trying to do:

IF all ALS files have been transmitted then
go to STEP_2
Sleep for 30 minutes
Go back to STEP_1
Enter the command “” - this shell script will rename all of the extract files accordingly.
IF all files do not have .TXT extension then
go back to STEP_2
Go to the directory /export/home/ftb_comm/prod/stage.
Enter the command nohup ./ YYYYMM & - this script will load all
of the FTB extract files into the staging tables.
EXIT shell script.

Can someone please tell me what to do, especially for STEP_1 above?
Attached is the script that renames the files, so you have an idea of what the incoming file names are.

One way..just a snippet
num=`ls ALS* | wc -w`

while [ $num -lt 26 ];do
sleep 30
num=`ls ALS* | wc -w`

echo "All the files have arrived"

Thanks, Dev, for the idea!

Below is what I am looking more for exactly:

num=`ls *ALS* | wc -w`
while [ $num -lt 26 ];do
sleep 1800
num=`ls *ALS* | wc -w`
echo "All the ALS files have arrived"
