Couple of questions may help the peanut gallery provide better advice:
- Are you comfortable telling us what field you're in?
- Does your field have seasonal swings?
- What feedback did you get from the initial contracts earlier this year? How did you feel they went? How did people react to your prices?
- What does "overqualified for C2C work" mean in your situation? Does it mean people won't want to pay your fees? Something else?
A few initial thoughts:
- you're only under-qualified if someone won't hire you; it usually has nothing to do with X years of experience. If your value proposition and price fit a specific need and the client believes you can help them accomplish their desperately needed goal, then that's all that matters.
- it usually (as in, almost always) takes a long time to start a blog and attract enough attention to make it turn into paying clients. Instead, I think it is much quicker and more effective to offer a low-priced, but helpful offer and then see what else you can sell to the same client.
- in general, you want to take what has brought you paying clients in the past and expand on that. Create new offers, revise your services/options, look for effective ways to reach your prospective clients, make it easy for them to hire you, and deliver some wins for your clients as quickly as possible, then find a way to sell them more services or use that relationship to find new clients.
