Melissa,
Its actually so funny. I have literally gone through this exact same process and have ended up with what i think is a great solution.
For your stand alone setup i would do the copy and paste thing from marketo forms. Especially if this is only going to be for a few more weeks.
For wordpress on the otherhand
There are two plugins you can get. One plugin you will need to pay for and one that is free.
This will allow you to have the form locally and push out submissions to wordpress.

Marketo Addon for
Gravity FormsOther form tools for wordpress. Although i think there might be better form tools on the market, cheaper or better,
none will come with the marketo connector out of the box.
The form builder is flexible enough in my opinion and they have support.
we are using it here simply
