I know this isn't properly a technical question but I hope this is ok here.
The question is simple: how much should I charge a customer for a Wordpress installation & configuration? Configuration simply means I have to install him a theme (which is not provided by me), various plugins and maybe edit some lines of code here and there to make the whole thing work fine.
I don't do this for a living, I'm just doing this for this single customer. He told me he wants to customize some features of the blog which I think will require a bit of code editing, but these will be small modifications, because I already told him that more substantial modifications will be billed separately.
I don't know exactly how long will this take, but probably just 1 day for the setup and some more days to adapt the blog to the customer requests which will eventually come up later
