Simple outsourcing suggestion that might work for you
I only maintain 2 VAs (part time) for my SEO/promotion activities and I'm paying only 2 to 3 hours for each of them everyday. That costs me around $120/month.
Be specific on assigning tasks.
I assign 1 VA in forum posting while the other one in Article directory/PR sites / Social Bookmarks submission
Forum posting
I have a list of active forums that allow forum signatures and I have account in all of them. These accounts I created years ago. I assign 1 VA to make at least 2 posts per day in these forums to keep my links in my signatures visible. The traffic from forum signatures alone gives my authority site more than 200 unique visitors a day consistently.
The second VA is assigned to do the following:
Article Submission
20 top article directories a day manually. I have separate writer who provides 3 to 5 articles a day to be posted in these directories. Submission in 20 directories can be done within an hour if he/she used to do it.
PR site submission
Same with article submission. Top 20 PR sites
Social Bookmark submission
Submission to 40 social bookmarks. Everyday, I post 1 to 2 review articles to my authority sites and my VA submit the links to these bookmarks.
Doing the above method for more than 13 months now, I could tell that the outcome is more than what I expected. Although their assignments may sound redundant to them, it can make their job faster and more convenient.
If you have just 1 VA, do not give tons of different assignment. I could only make him/her inefficient and ineffective.
I was the only one who do all the above tasks before but when I started making money, I passed it to my VAs...
Just a suggestion based on experience. Hope it helps.
