Send him a letter of demand. Give him 30 days to finish the job. Or whatever you deem is suitable. Show him that you are serious and not going to put up with nonsense.
In the past, I have sent him several documents stating that I want things finished by a certain date and what I expect to happen if it doesn't happen. He just ignores those.
I've also recently asked him to sign a proper contract with a fixed project completion date, to make up for the fact one was never signed at the start of the project, which was silly on my part. I signed it myself and sent him a copy on 24th March. The completion date was set to 4 weeks later - 19th April - i.e. tomorrow. He just ignored the contract.
I've also keep reiterating that he's been paid $6,490 and delivered nothing to me, which is just not fair. He just brushes that aside like it doesn't matter.
He keeps talking about what he terms "monstrous" lists of changes to his page drafts. However, most of the changes are because he isn't reading the design spec and he ends up stripping out critical components from the original web pages he is redesigning/refreshing. Other changes are simply to do with the layout. It's just static HTML/CSS, nothing complex. How hard can that be, particularly when you have an existing website with content to base it on?
While all this is going on, I'm noticing he is doing work for other clients based on his postings on other websites. Maybe those people only pay him as he completes work, hence they get first priority if he's suffering a major cash flow issue. Maybe it's all to do with financial survival. After all, he's not getting any more money out of me, so I get the lowest priority.
I do think though I need proper legal advice. Can anyone recommend someone that doesn't charge an arm and a leg, has an understanding of these things, and is based in Melbourne? I did consider going down the path of legal advice a few weeks ago, and sent a couple of lawyers I found on the web emails requesting a quote for them to look at the situation which I briefly outlined, but none have gotten back to me. So I don't know if they are either very busy, whether they are just not interested in this sort of work, or whether they believe I have very little chance of success, so they won't bother getting involved to begin with.
