Modifying a Darth Maul single hilt

[Darth Vadion]

Hey I would like to know if there is anyone who is able to modify a single hilt maul saber for me, all I was is to replace the string LEDs with a single blue LED in the hilt and for the saber to be able to have a removeable blade. If there is anyone able please let me know what it would cost as well as any other info thank you all.

There is Ultrasabers: they can convert your lightsaber with a Luxeon LED in the hilt and with removable blade. I think that the cost is 99$ but I'm not sure.
