Help me launch my new business!

People have been telling me for years that I should set up in business on my own, but I've always been too afraid to do it.  Last year, just because I thought it was cool and technological, I bought myself a 3D printer and I can honestly say that although it's one of the most unreliable things I've ever bought it's also been one of the very best.  It's unlocked a massive store of creative potential in me and now I want to make something of that potential.

The idea I have is to provide a dual service; on the one hand I'd do traditional graphic design (calendars, stationary, leaflets, posters etc.) for private and business customers, and on the other hand I'd provide a bespoke 3D design and printing service for small and unique items.  Need a special promotional item for your business?  Using your ideas I can make something memorable which explains what you're all about.  Getting married?  I can design you little card holders, party favours, or even 3D scan you and your fiancee so you can both be on your cake.  Want to propose to your girlfriend, who is a massive Pirates of the Carribean fan? I can design you a box for your engagement ring shaped like a pirate's treasure chest.  I can design for you something NO-ONE else in the world has, which will be yours forever.  The possibilities are endless.

The only thing that is stopping me launching this business is the fact that I don't have a RELIABLE, professional-quality 3D printer and the specific accessories for it.  And thus I turn to you, my friends and potential future customers, to make this a reality.  Any help you could provide will be eternally appreciated, and I will design something special, just for you, in return!
