There are many things that you can do but based on your explained situation I would dollar cost average into a mutual fund or even an ETF. That way you're not exposing yourself to too much market risk at any one time. I'd also consider getting yourself a reputable financial adviser if you're asking for people's opinion on a site like this. Your money is too valuable to get random opinions without really knowing your specific financial needs, goals and overall situation.
Diversify across asset classes, such as a commodity fund (10%), a currency fund such as FOREX (yes, that's the symbol), some high yield bonds, REITS, emerging markets stock, and so on.
I would wait until my bank opens and go in for an appointment, but set up the appointment on line during bank closed hours.
