Stay at home moms/dads, especially the ones that used to always hang out at the "main" forum
Work From Home - Work at Home Jobs, Recipes & Articles For Moms - WAHM.com, they were the best people to work with for a lot of marketing-related projects compared to using freelancing sites in my experiences (haven't been on the site in awhile though no idea if things have changed). Generally they're decent-to-good writers always hanging out there, most social media savvy and active in niche forums, easy to get in touch with on chat programs and no problems with general project-management software and familiar with basic marketing tools, I'm sure half of them have their own blogs and social media presence, no communication-language barrier major time-difference problems, lots of them are VERY interested in learning more about online marketing and online businesses in general. (This is awesome and can be a real asset and you don't get this kind of genuine interest from people on the freelance sites just grinding out jobs).
It was way more efficient to hop on that WAHM forum and describe the kind of projects you're doing and looking for help with, than wait around on freelance sites, for these kind of microtasks and projects you need help scaling. You will get lots of people PM'ing you for info if you're professional and clear about what you're doing and who you are, clearly state kind of payment and frequency of payment options, explain frequency of work, give links to examples of type of work, etc.
In order to post these kind of projects/jobs in the main "discussion" areas, the best approach was to post the details of the work that you need help completing, don't just post job ads on these "general discussion" forums, your post will likely be removed or moved to different rarely seen section. Become a member of the forum, answer some questions, make some good posts.
Make a post stating you need help with overflow work on a new project, how you're excited about a new project you're working on etc. Otherwise those job ad sections were just way too crowded to actually get noticed and interact with people looking to help you out. Was way better to just discuss what you're doing in the discussion areas rather than post a job on those places designated for job postings only in my experiences, they're filled with scams and most of the people looking for legit daily work weren't even browsing the specific job ad sections much or it was just the same five work at home companies spamming the same stuff over and over.
If you can pay weekly/every few days for projects you will attract a ton of people too. The key in my experiences was transparency and providing good training/reference material for them. You can also usually very easily go through a lot of their profiles to double-check how active they've been working online, see what kind of work they do, links to social profiles, blogs, portfolios etc.
The people helping you out with projects will post about their good experiences working with you in the main discussion area that gets serious traffic, and then the whole thing can turn into a lot of referrals that you can use for all kinds of projects, but totally depends on your business model how effective these kind of "generalized" rather than "specialized" workers can be. I pretty much exclusively used
