I have my first offer, what now? Should i be worried?

[mojo73]

Hi all,
I have had an offer to purchase 1st Australian and International rights to some of my images for a calender at a mutually agreed $rate.
It has been requested that i send a DVD with around 50 of my best images (full frame, straight off the camera, no processing or watermarking) for evaluation and selection for the calender, then have been promised that the DVD will then be passed on to a magazine publisher whom is said to be 'possibly interested' in getting me to do a future shoot.

My question is this:

Q: Should i be worried about sending full size, un-watermarked images on a disc? Or should i be sending reduced size and water marked images first?

Sorry if this is a repeated question, but i browsed for ages (Some great info on here btw) and couldn't find anything quite as similar to my situation.

Many thanks in advance for your replies:)

Who are they? Someone here may know them. Reputable? In the phone book with offices you can visit?
If you can't answer that to your satisfaction, I'd send full-size, BIG watermarked images.

A) Make sure you have them copyrighted legally so if they use them without payment you can prove ownership.
B) Yes, make sure they are reputable. I upload to a few magazines, not really full size but pretty big and they use when they need to, then pay me after use. BUT, they are big professional businesses, not some guy wanting to make a calender to sell on EBAY :)

Mojo-

A center 50% opaque watermark to make the image unpublishable is a standard practice of many image and stock houses. Only send out hi res images with watermarks prior to payment. I also require pre payment for any new client with net30 after that.
