DM to larger list or hit a smaller list multiple times?

Im about 3 weeks into my wholesaling journey with no leads and im just trying to figure out the best way to use my limited capital. So far I've been targeting a list of 700 High equity, absentee owners. I've sent them all post cards, and i've cold called 300 names in the list with no leads yet. I plan on calling the rest of them this weekend. After I call the rest of them Im looking to send out another mailing. Would it be worth it? Im thinking it might be better to save the money and just start back at the top of the list and cold call them all again. Im really just so hungry for my first deal, but my time is limited as I work 50 hours a week as well as attend community college. Thoughts/tips?
