Just want opinions on how much I should be charging my client. I run, maintain and update their website. They send me stuff usually like every other day or so. usually pictures and general updates in a CMS system. Basically They expect me to be on call 24 7, no matter if its a weekend holiday or whatever. I try to be fair with what I charge them but I dont think im charging enough to be at a company's beck and call all the time. So how much should I charge to be on call like this all the time? Any advice is much appreciated!
