Their last product went from the drawing board through prototype, testing, redesign and into production in about 5 weeks. I'd say the developement time line for the cart should be the same or less and the wrench just a matter of a week maybe two.

The biggest hold up right now is financial, they just bought an entire product line so aren't in a good position to speculate and I'm beyond broke at the moment so I can't afford to back a prototype cart for at least a month. I'm sending them a mock up of the wrench next week.
