Tell me about it! This is what brought me to this forum today. I have a reseller account with a hosting company. I built a Website two years ago for a lady who is a small manufacturer of a single item. It's available in many "flavors" but it's just one item. She has a shopping cart, so there is a database, but she is basically a wholesaler. Since before the site was compleated, this lady became a royal PITA. She is totally without any knowledge of anything that has anything to do with computers or Websites, so I wound up loading her "store", and agreed to do maintenance (for an hourly rate).
Long story short, I found out quickly that she wants more than she is willing to pay for, complains when things aren't done as quickly as she would like (but she can't do it herself), and every time sombody can't place and order or get an email through, she automatically assumes there is something wrong with the Website or my hosting (we use ZenCart and FormMail, two open source programs that work very well). I find that I spend so much time doing her "stuff" that I barely have time to sell other design jobs, which is what I want to do.
The last straw was right before Christmas when she asked me to do an online catalog for America's Mart show in Atlanta (this week). After ten pages, and many hours doing creative work, she pulled the rug out from under me (when she asked for a couple more pages, and I told her I was charging her $50/page, which was cheap) and said she was going to give the job to her "graphics designer". I told her, "wait a minute, I have many hours in this project." She agreed to "pay for my time." I sent her a bill for $500 for the ten pages, which she had had me send to her "graphics designer" to complet the job.
When she got my bill, she called me, and was furious. She said she couldn't do business with me any longer and would be looking for a new host! (Hooray!). She paid the bill. She is still on my servers, suposedly looking for a new host, and has someone she calls her "help" (that's what she called him in her email) that will manage her Site, and not to bill her any more. I'm glad to see her go, but she is still on my servers as of today.
I have others that I host (I built their sites too) and I never hear from them.
But, this is an experience that makes me question if I want to offer such services ever again. As of right now, don't think so.
And now I think I'm going to sit down and play a little flamenco on my Alhambra 7fc flamenco guitar!
