How much do you think it worth?

Recently, i had create a wordpress blog using co.cc free domain and free hosting, this mean I did not pay anything for those. At the same time, a few idea was pop up in my mind about doing some installation services for wordpress by include this free domain and hosting.

Maybe I can promote it to anyone who want to try blogging using wordpress but do not know how to install it or find free domain and hosting for wordpress installation. So, how much can I charge for my work? $10 or $5? Or maybe less?

This work including:

1)New email set up for host and domain.
2)Free co.cc domain (or maybe other free domain such as uni.cc|tl.my|co.nr)
3)Free hosting
4)Wordpress Installation (maybe add some free theme and usefull plugin)

So, do you think this can attract newbie|beginner to hire me to do the job? How much do you think it worth?
