I just landed a pretty big SEO Client. We sealed the deal on my consulting fees (a strong 4 figures monthly), but they have asked me to give them a price on "maintaining their website" for the year. I am not even sure what this should entail really, much less what to charge. I do want the extra cash though and these guys are willing to shell out. I need to make them a separate proposal for the website maintenance. Any suggestions as to what I should include and what I should charge for it? Any help would be much appreciated. I should also note that I am capable of web design and some coding. I know how to do the stuff just don't know what to include and what to charge. Need to make a nice detailed proposal.
