I have the following and am thinking of selling as a bundle:
Canon EOS 300D 18-55mm kit boxed (complete contents)
Tamron 24-135mm F3.5-5.6 AF SP AD Asph (IF) Macro
Canon leather case
Canon RS60E3 remote switch

How much do you think I could sell this lot for?

It's hard to say since you're including the Tamron lens. Personally I wouldn't bundle the Tamron in with it as you are forcing someone to overlap focal lengths and you'll likely get more for the lens by itself anyway.

For the Canon stuff I'd guess around £250 ish.
