Customised Led To A Spice Jar Cover

Hi,

this is a mini project of mine....

any idea where can i find someone who can add a LED light to the base of a spice jar cover (silver cover of the jar)?

Basically im trying to keep a small fish in this kinda of spice jar.

So im thinking of attaching a small LED to the base of the spice jar cover which can be turned on and light up the jar once it is filled with water (meaning the LED must be able to withstand water).

Definitely a small job but just dunno where i can find some help.

Thanks!!
