Getting Loan to buy Shares in Company I Work For?

I could have an option in buying shares in the company I work for, buying a fraction from one of the two current share holders. I've money in the bank, but not to fully fund what is on offer. Any recommendations in how to loan the rest (apart from finding a wealthy family member). The loan would be under £50K. Another piece of information that might be useful, I currently don't have a mortgage as I paid that off already (so can't do any restructuring with an existing mortgage).

Thought it might be worth posting in here on the off chance anyone has any experience in it, before I spend a day on Google.

 

I looked into something similar a while back and ended up chatting to someone about property finance Manchester for a different investment. They explained how loans connected to shares can affect your credit and what kind of security lenders might expect. Might be worth talking to someone with experience in both business and personal finance to see how it lines up with your goals, especially if you're tying it to your current job.
