I wish I had a team. All solo for me and no money to hire anyone. I'm still confident I can make a huge success of my project, it would just help a great deal if I can get enough backers.
Some ideas: You can still leverage your efforts with some automation. I mainly use Buffer for twitter/facebook/g+ marketing. There's also Hootsuite.
You could also try bringing on an intern for the campaign/business. You could get a $3-5/hour rate if you were to use a virtual assistant overseas (I use several).
You could involve a partner (equity percentage or campaign fee). Likely, this would work best if you know the person in real life, not online.
All that said, I've seen plenty of solo creators be successful on Kickstarter .
