How much do i need to charge for site similar to ( without psd only html and css file)
No offense but i dont think you can charge much, if anything for sites like these...every free template you can find on google looks better then these...sorry i have to be so harsh but thats the way i see it.
well then this is a bad example of your skills
anyway i am making a site at the moment,using a three color scheme
black and dark-blue for the site,white or light-gray for text
you check the similar projects with the help of some freelancers sites after that you get a brief idea about it.
