Php 4.4. Script

Hey, I'm interested in your project. I have 5year experience. I can share with you my work experience. I'm always available here .so  Please send me a message so that we can discuss more.

We need of little script.. We have a big text file in ftp folder, script need to: user submit data --> our system copy data into ftp folder--> check this file, and split lines into different smaller files. Then copy little files into other folders defined by user. Example: User will select to have 1000 rows into folder 1, 4000 row into folder 2, 6000 rows into folder 3 etc.. Script will check if this folder exists and will move little files. Plz REMEMBER : PHP VERSION IS 4.4 AND WE CAN'T UPGRADE.
