Hi Nicsx and welcome to the forum,
This is much more difficult since Brexit unless, as DUI has said, you have an Irish passport, or would qualify for one by virtue of having an Irish parent or grandparent? As your son in no longer a minor, I think he would have to apply for his own visa, but it would be worth checking with a Spanish Consulate in the UK or an immigration specialist whether, as a direct family member who would be living in the family home, he can apply as your dependant.
This link to the Spanish visa website gives general advice about the application procedure, and a link to the different visas available:

For what you've described, you could apply for a work visa, either as a business owner or self-employed ("autonomo"), but these have quite onerous document requirements, including submission of a business plan. Depending on your finances, an easier route may be to apply for a Non-Lucrative visa for the first year, giving you time to set up your business (but you won't be able to earn income during that period) and then switch to one of the working visas. To apply for an NLV, you'll need annual 'passive' income of €28,800, plus €7,200 for your son (if that is permitted), i.e. €36,000. As you're not pensionable age, you'll also both need private health insurance. Once your business is up and running, and you've switched to a working visa, you'll be making social security contributions, so you'll qualify for State healthcare instead.
There have been some changes this year to social security payable by the self-employed in Spain - this article is a quick summary:

Visa applications have to be made at a Spanish Consulate in the UK (London, Manchester or Edinburgh, depending on where you live). Some forum members have done this themselves, but given your proposed plans, I think it would help you to speak to a specialist immigration company in the first instance - Upsticks has been recommended by other members:
