We put 'interrupters' on my wifes BF. She wanted drop bars but isn't comfortable braking with them.
I agree with Vik's advice on learning to do some of your own work but this would need to be done by someone with some experience.
Here's a link to what they look like. They're extra brake levers on the top part of the handlebars, seen best in the third photo.
