Hi there. I can get this done ASAP for you. Just to confirm, you wish to change the upload limits not post limits? GoDaddy don't have a limit for Cpanel users, however, it's worth putting a limit there. Can you tell me what you need to upload so I can work out an appropriate limit for you?
I am available right now to do this, so if you would like to chat about the particulars, I am ready to go!
Thanks
Danielle
