What is a young PR student to do.....?

Well I have just finished a weeks placement (well....4days to be precise) at Quest PR in Harrogate. A small but up and coming firm who have just won the CIPR Best Small Team Award for the 3rd year running. A graduate from Leeds Metropolitan University now works there, Mark Drury, what a small world it is! Upon leaving though they have left me in a bit of a quandary. We had an "exit" interview about how the week progressed and they have presented me with a rather unbelievable offer. They are offering me a graduate job upon me completing my course at Leeds Metropolitan University on the condition that I do my one day a week placement with them for the rest of my degree!!!! Upon first thought this was too good an opportunity to miss, a job waiting for me? A guaranteed placement? but I am in my first year. I merely studied the subject for 3months would I not be signing myself off just a little too early? This was my concern and it would limit my experience of different sectors and different companies throughout my 4 year degree learning period. But is this too good an opportunity? Could I learn all I needed to learn from other placements here? Well for now I'm going to ponder on it and speak to friends, family and lecturers to see if there is any guidance and advice to be found. Any help would be gratefully received!!
