Do I need to be aware of any legal / tax issues?
Can I just start selling kits here and there, or do I need to make an LLC first?
Should I sell them myself, and if so, use an e-commerce platform, or just do it all manually?
How much work is it to support the platform? Do any of you spend significantly more time helping customers than you expected?
In general, is selling kits for good projects a good way to make money? Or is it more of a waste of time and money?
