hmm, I could think off these few factors.

Is the design complicated?
Are you developing a customised blog engine? Or, using an existing blog engine?
Do he/she requires you to maintain the blog for a long period?

Well, I guess its common sense to give a relative low price tag for a student/personal blog, but you will need to know what kind of blog he/she is blogging. If he/she already got a very famous blog (blogspot/wordpress) then you might as well charge a higher price tag since he/she knew that a good design could definitely boost his/her incomes
