How do I send 5000 dollars to someone?

Excuse me, could you please clarify the process for sending 5000 dollars to someone? I'm a bit unfamiliar with the different options available and would appreciate a step-by-step guide. Specifically, I'm wondering if there are any fees associated with the transfer, how long it typically takes for the funds to arrive, and if there are any security measures I should be aware of to ensure the transaction is SAFE and secure. Additionally, are there any restrictions or limitations I should be mindful of when sending such a large amount of money? Thank you for your help.
