Depends on how long you're willing to invest for. Broadly speaking, the best (by which I mean, more reliably repeatable) way to make money from market corrections is to accept them as a fact of life, and not sell in a panic when they happen, such that the money you already invested can ride back up again.
Put another way, just invest your money in one or two broad, low cost index funds with dividends reinvested (maybe spreading your investment over the course of six months or so) and then let time do its work.
Have you worked out how much you've missed out on by holding your money as cash all this time (I presume you've been saving up a while) instead of investing it as you went? I suspect that by waiting for your correction, you've already missed out on more than you're going to make from that correction.
