A picture, a moving one at that, is worth a 1000 words. If possible, attempt to show them a video or send it to them.
One of your greatest resources may be the bow companies themselves.
Start by creating a list of people in your government who will determine what will happen and provide that list to the bow manufactures. Advise the manufactures of the who what and wheres of any meetings.
You may help influence them with information like the potential number of hunter, the make up of the game animals in your country and what a good market would open up to them with an entirely new area of sport. They love selling more equipment and have all the factual info you need to sway the officals.
I'd imagine you could do all of this in a couple of hours on the internet. You may open some doors for your self along the way. Do not stop at bow makers, contact those that sell camo, calls, scents, stands and make videos.
Good luck.
