I have a lot of good product ideas, and some partially built ones. But I don't have the cash, or the marketing / sales experience to actually be able to sell them.<p>I'm wondering if I can just build them and sell off the code to make some money on the side.
Making a lot probably means it's not a side project anymore. Do you mean side to begin with, or ongoing? The latter will limit the attention you can give it.
find the most simple sass tool that is generating profits. Copy it and make sure product is solid. Sell it at 30% of their price. Stay lean. It should cover for your income at least if you do it right.
