If you are planning to sell this stuff out of your garage, expect garage sale prices.
Also, are you far enough away from your neighbors that they wont complain about loud machinery
Is your home/garage sitting on 'commercial property' zoning.
Have you gone around to places that sell similar items and see how much they charge? If so, do you casually drive by from time to time to see haw fast this stuff is moving?
Will you have to rent/lease commercial property to build/display/sell your merchandise?
Are you going to sell your merchandise to a retailer who will give you less than 50 cents on a dollar?
If you want to build on a decent scale, you will need to hire people to help build, clean-up, help move, pack and ship, etc
Will they supply you with a verifiable list of other similar business franchises they have sold where you can actually visit these operations and meet the owners face to face on their location
My final question is: why would you even consider a franchise on a labor intensive woodworking business?
Lots to consider here.
