Javascript code for shipping days calculation

I need a javascript function to take the current date and time and an integer number of days and add the two together to return the future date. The function should exclude weekends and holidays. The code should also incorporate current time as explained below. It should basically be like this, but without the datepicker portion of the code. I had difficulty getting it to work without the datepicker portion.

If you are interested in this project, please mention that you have experience with working with javascript dates in the response so I can filter out the best entries. Thank You.
