what a waste of time I had some guy who was interested in having a website built. we agreed at $500 and I sent him a contract. in our meeting, he said he would be sending me the signed contract and check within 2 days. meanwhile, he wanted me to create facebook and linked in. He also had me set up his domain and hosting, and I created mailboxes for a bunch of people in their firm (email@example.com, firstname.lastname@example.org, etc). I did not mention any price for this, but I thought I would work for free to impress them or I thought maybe they would pay me a tip on top of the $500. any decent human being would. well, it's been a week and I have not received signed agreement or the check. they are also not answering my text messages. what a waste of time. what could I have done to prevent this? what about revenge?
