I would prefer some service that works with shared withdrawal addresses, so it is not blockchain visible where the bitcoins came from.
I need at least 10 different addresses only once.
Oh then CoinsBank should work for you. You can create as many addresses as you want as far as I know and you own the address indeed (you can use it multiple times) but there is other transactions going on on that address If you check the blockchain and when you withdraw too , no one is going to know that It belongs to you . It's basically a mixer for free .
