Yes, you should automatically get FULL rights to the content and thats what you should ask for at the time of ordering it.

'Id like to order some exclusive content shoots with full rights'

That basically means that once the content originals and encoded/touched up versions are delivered to you, you can do what you like with them, web, magazine, dvd, resell, whatever you want

Depending on who you order from, expect to pay around 50% of the total order upon ordering, unless the shoots will be spread out across several weeks/months and 50% upon deliver and completion.

Never pay 100% upfront, if someone wants you to do that, they are in the wrong business and i dont think i have ever been asked for 100% up front for content shoots.
