I'm sure it must be out there already in some form, but you might want to give a shot at "uber for day laborers". It seems to me like there are opportunities on both the supply and demand side. On the supply side there its lots of room for improving gig hunting and payment assurance for laborers. Staffing agencies are of course in this space, but are pretty inefficient and catch only a small fraction of potential gigs relative to something like craigslist (which of course, has the downside of potentially unreliable payments). On the demand side, there are definitely niches for short term gigs where a company needs to scale up or down quickly (last minute work, no shows, etc). These quick changes can be hard for staffing agencies to fulfill, largely due to inefficiency in recruitment, even when the laborers are already in the talent pool. If you don't have any experience with this area, its really easy to do so: try to find some ditch digging on craigslist and see how many gigs you can do before you get stiffed or otherwise mistreated (won't take long). Also, use that pile of cash you have in the bank to try to find contractors to paint a house, clean some toilets, etc. and you'll start to get a sense for problems in the labor pool.
