They will supply you with a list of courier companies, you can get this for free on yell.com or any local business site..etc..please be aware most courier companies want van owners only, not cars! also courier insurance is VERY expensive so be really sure you want to do this type of work, good luck.
I have to agree with djtdjt on this.
My Grandson got stung this way,he paid nearly �40.00 to such a company,and what did he get in return?
40 (very badly) photocopied pages from a book printed 10 years ago,that he could have got from the library or a boot sale.
As djtdjt says,just beware!
