Hm... Well, you could go that route... but there is more to ordination than getting stuff done online. And being an online minister is different than being an in-person kind of guy. Much different.
I don't know what the laws are like in the States, or even in the rest of the world, but I know that in Ontario (and also British Columbia, both provinces in Canada), in order to be able to legally perform marriage ceremonies that are recognized by the state, you must be an employee of a denomination or group that has been in existance for at least 25 years. And in BC (among other provinces) you must also agree to do homosexual marriages... though that is currently in flux for the entire country. Much prayers will be very much appreciated...
What I know some people do, and I intend to go this route, is to pursue the option of having two separate services... a civil service, which is the legal contract that you are signing and the registration with the country in saying that you are now married, and a church service that may have no official paper work, but is a significant ceremony for the couple before God...
Regarding ordination by the traditional route within any given denomination, I think you would need to go through the hoops of that specific denomination... and correct me if I'm wrong, but I think there is a stipulation with most denominations that says that you must already be serving in ministry for at least a year, and that you must have taken courses x, y, and z at any one of that denomination's recognized seminaries. (or even an entire degree at that seminary)...
