There are actually Fixed Term investment schemes in the UK that pay 10% or 12%, subject to whether you want bi-annual dividends or not. This is governed in the UK and has been running for 20 years without any issues. The minimum investment required is 25k so would probably suit your budget.
I can put you in touch with someone who can explain in more detail if you wish.
I’m not selling this type of product but I have invested myself so I can vouch for its authenticity. The Fixed Term investment period is only 2 years but you have the option to renew as long as you are happy with the returns.
If you choose the 12% rate, your money would practically double in 6 years.
