You could split the file in between 10 to 50 pieces which will give you a chance to upload it and give other people a chance to download it easily and without any problems, even if their computer crashes. (I've known a few people who were downloading large files and when they to to the half or something like their computer crashed and they had to start all over. By splitting the mod into multiple pieces this, even if it happens, will allow to continue your download without having lost anything. Same thing for you when you upload.)
Only negative aspect of this is that people will have to search for the next file everytime and you'll have to work a little bit more by splitting the file.
