The money is most certainly in the list. If you're at all interested in online marketing, setup email software and create a lead magnet that you can use in your sales funnel. Then, build up that list. It's often said that you can expect to earn about $1 per subscriber per month. If you have a list of 10,000 subscribers, that means you can earn roughly around $10,000 per month. You will need to deliver value and not pitch them on every email, but it is a very achievable goal in a short period.
Salvage and resell. Do you love antiques or have a knack for finding valuables at flea markets or yard sales? If you do, it might be time to consider salvaging items for resale – or even scouting out antiques to sell for a profit. While you’ll need to spend quite a bit of time searching for prospects and spend some money buying upfront, you could easily turn a profit if you know what you’re doing.
