You're in luck—that's already been done.
If you click on the tab within the enotes study guide to the play that reads "eText," you'll get the script of the play. Click on a specific act, and then scene, and you'll see it in parallel columns. The column on the left gives the play in Shakespearean English; the column on the right gives each speech in modern English.
You can also click on the "eNotes" tab and then on "Summary and Analysis" and get, well, a summary of each scene, and an analysis. If I were really stuck, I'd read the summary, then read the modern English version.
There is a translation for act IV scene 3 in the following link
