Sorry, I saw that he's on a student budget and know that this is a thing Art Dept constantly does.
If you want a more sound professional advice, then ShareGrid/KitSplit is your friend. Aputure 300Ds can be rented for about $50-100 a day/weekend. As for batteries, I highly recommend trying to rent an extra set of v-mount batteries to eliminate the need for a genie/suitcase. As mentioned before, use either a bounce or diffusion for an atmosphere light. And again, haze/smoke is your friend in this type of situation.
Also forgot to mention in my first post, have some sort of chinaball/light dome set up to help key the talents faces.
