Personally, I'm not a big believer in the keywords in domain name for SEO. I'm sure it plays a positive role, but it's still just one factor. Something like "more money making com" will still be of help only on a limited number of pages you create, because they will actually focus on other keywords/keyphrases.
The main problem with the domain you currently have is that it can easily be misconstrued as being a site that is all about jobs opportunities. It may turn some people off from clicking on links to it: "I'm not looking for a job, I want to make money on my own".
