209115 Increase video upload limit

I currently have a website at [login to view URL] Currently if any member is trying to upload a video over 20mb it gives error. I would like this error to be corrected and upload file size limit to be increased to 900 mb. This is super easy for php experts. So serious bids that can get the job done quickly will be considered. Also price should be low, since this is a simple job. Payment will be made after the job is completed via escrow.
