Having an LLC is a great idea. But when putting the project on Kickstarter, use your name and not the company name. It lets people know there's a flesh-and-blood person there putting the project together, and there have been others who used corporate names to hide behind as they were ripping off their backers, never delivering a finished deck. Just ask anyone who's ever dealt with Altius Management (Bicycle Asylum) or the Department of Design (Founders).
The TOUGHEST part of a Kickstarter project is fulfillment, in terms of physical labor. Funny you should mention Jackson, since he's now running a fulfillment service which caters to the playing card community. I've heard of people using other companies to do the job but they don't generally understand the value and rarity of what they're handling and you tend to end up with a good deal of returned, damaged decks. I think Murphy's Magic Supplies, a wholesaler out of California, also does fulfillment services. I do know that for a fee, they can make gimmicked versions of your deck - stripped, invisible, forcing, Svengali, etc. They do that for a company I know and the results are good quality.
Of course, you can save a few bucks and do it yourself, but it's a lot of work - if you make a very successful project, you could be waist deep in packaging materials and decks for a few weeks. It's best to plan a work vacation around the time of your shipment arriving from USPC. Those who didn't often caught hell from their backers as they tried tending to shipments only on weekends, nights, between classes, etc. (It's why I'm always wary of a project launched by a kid in college - there's no way to know if he's scheduled the necessary time and they don't have the freedom to take a vacation when it pleases them.) It always helps to have capable friends or relatives help in exchange for pizza and beer, as long as they don't get drunk and spill grease on the packages!
Kidding, of course, but you get the idea.
Paul Carpenter has commented in the past that one of the most important things he does before launch is to take out a spreadsheet and account for every single possible cost he can run into. As he describes it, it saves him a lot of hassle later and his estimates have been pretty accurate.
Oh, and most deck designers running a KS project will lose money on the one- and two-deck packages. It's just how it is, when factoring in the costs of production and shipping. You'll make it up in the larger packages. Thus, do what it takes to encourage your backers to back for more decks - introduce a second color, a special edition, a trick version of the deck (marked or stripper are popular), add widgets that people want, etc. Upsell the hell out of them. Jackson Robinson's Federal 52 project started out as just a single deck and went on to become nearly a dozen decks spread out over two projects. I'm thinking that he had far fewer single-deck buyers than most projects do!
Consider a service to help on the back end with the management of add-ons. Again, Jackson is a good example of this. He used Backerkit on the second Fed52 deck project, and I could tell that it was a godsend in that it allowed his backers a chance to spend EVEN MORE money on his stuff after the project was already closed - I personally took the plunge for a Spade t-shirt. So despite the high numbers his project reached in KS, his actual take was somewhat higher than that!
