You have left nowhere like enough for the software.
The industry standard for publishing is Quark... £1300.
Or you could use the package my partner uses Adobe Design Collection £799 before VAT but a self employed graphic designer should be able to claim the VAT back (you may be pushing your luck with the tutor there though)
InDesign will do what Quark does (and in my opinion its much better)
Acrobat to send samples ... and for some printers
Photoshop and illustrator are pretty much industry standard anyway.
