I won't tell you to seek the advice of an experienced immigration attorney, since you already know that answer. What you should KNOW. Your case is far more complex than it appears on its face. Yes, you are subject to the 3 year bar and yes you better have a boat load of evidence. You know this. However only an attorney can evaluate ALL the facts of your case. There are many other reasons that will cause your case to be denied. Perhaps, you can purchase the latest edition of KURBAN, a wonderful immigration treatise that costs over $400.00. It is not easy to stay on top of a law that has many minefields.

The 3 year bar does not apply to people who are granted voluntary departure by an Immigration Judge. Also, the three years bar is measured from the date of the physical voluntary departure. So, it appears that there is no 3 or 10 year bar in your case unless there was some prior overstay issue. The appropriate thing to do it to ensure the consular officer has all the documentation to establish the relevant dates.
