I think it's great that you outsource your tedious activities to make time for more major activities. I'm fairly new as well and I sometimes feel that I could be doing so much more to grow my business.
I do not use a VA but I plan to once I establish myself in my market. But for now, I'm focusing on building my web presence as well as maxing out other channels of marketing other than direct mail. I am also networking a ton and assembling a power team. I've met with attorneys, realtors, contractors, other investors, accountants, etc. Building your network is huge and from what I've learned thus far, it opens the door to a lot more opportunity.
I look for any way I can gain an edge and make my business better, especially small things like reading books on building relationships with people (How To Win Friends and Influence People - I would definitely recommend it!), taking a member of my team out for coffee, or practicing my negotiating skills. I look for any opportunity to set me apart and help me provide value to the marketplace.
Hope this helps! Good luck with your business.
