I would suggest you get out and meet the general contractors in your area. Try to seel him the garage doors along with a low cost installation. This way you will be able to sell in bulk, and shipping this way should eliminate your problem.
THe only other way I can see to do this is to get in to independant stores. this way you can make one shipment to their warehouse and thay can do the distribution from there.
Hope this is of some use to you.
Cheers,
