Hey all. So i have a car rental client in the states for who i did seo work couple of months ago. Results are ok, client is now lower page one for the phrase *car rental theirtown* coming from page 5+. Made a deal for a couple of k and now is the time for a 'monthly package'. He paid half upfront bi weekly and we agreed that when he would hit page one i get the other half. Now the f*cker tells me to go f*ck myself, and changed ftp passes etc. Ok so what i am planning to do is make a reviewsite about his company that will outrank him for sure with some bad rep. Only thing is that i want double the cash he still owes me before i move/change that page. First i want to give him a last chance to pay me the other half of the deal within 3 days, with the above message. Since i am from the Netherlands i am not sure about the legal way of this in the US. Can anyone shed a light on this one? Thanks!
