I've taken on a new social media client who I initially quoted my normal rate. This client needed daily posts on Twitter and FB for his own client, told me he was in a bind and needed someone to start quickly and help him out or his client would leave him. But my fee was too high and he offered me a lower amount that he was willing to pay. Because I'm a nice person, and I felt bad for him, and I could see potential for more work coming from him in the future, I reluctantly agreed to the lower price. Once I agreed, however, he threw in 'since you are already going to be in FB please post a few things on my two personal FB accounts'. This client doesn't think it is necessary to pay more for these additional postings. Then on Christmas Day, emails to say he is concerned that the posts are not attracting enough 'likes/follows' etc and wants me to increase my efforts, and that if I did he had three more client accounts he'd like me to attend to.
Besides the fact that such social media activities do take time to see results, researching, writing and posting the posts, monitoring the sites and reaching out to attract more fans and followers in these three particular niches is taking more time than I initially estimated. I've politely mentioned to him that for $200 p/m he is getting what he is paying for. The client does not like this and is reluctant to pay more until he is seeing increased results and is insistent that only posting to FB shouldn't really cost any extra. Now, I've only been working with this client for a short while and still haven't been paid a cent, even though I've sent him an invoice.
How can I politely raise my rate to actually compensate me for my time? I know now I shouldn't have agreed to such a low figure in the first place and won't make such a mistake again.
