What type of business is it. Sounds like you could take it Without spending a penny.

Sounds like there is no urgency so I would forget the investment aspect for the moment and use the time wisely.

Identify a number of things you might enjoy doing that could potentially turn into micro business’s.

Use the electronics skills and knowledge of electrical components to make something with a view to selling on etsy.

Identify bundle electrical components which are always brought together and market them on places like ebay

Identify drop shipping opportunities with zero outlay and market them on websites like ebay.

Try a number of things to upskill yourself across a range of activities.

If there is no urgency and you have no real need to invest the 10k, do not invest it and instead invest time in yourself to learn things and find out what you enjoy doing that could be a future income.

Many of those biz can be subcontracted and you might want to research a defunct company called react fast (uk) who were managed by business people who had zero experience but plenty of contractors who done the callouts. They sold the biz.
