I think you can pull off #6 for under a grand. Some digital prints mounted to 1/2" leftover mdo that was cut to shape. 4x4 posts, The brackets and finials could have been objects from Jim's shop ( this is an imaginary contest, right?), plus some paint ,concrete, and mounting hardware. -just about $300 in supplies,leaving $695 for design, production and installation
1 hour design- ( the design is OK, just looks like clip art and gradients to me)
2 hours production
2 hours installation.
I would charge more than $995, but I could do it for that price and still make some money.
Alot of the other designs are great and I think they would more cost effective and profitable.
