A couple of things hurt the credibility IMO:
* "Client has $300+ budget" < This gives a very bad impression. I wouldn't want to hear from any client who has a budget in the vicinity of $300.
* Wordpress, PHP, Website Dev (?) but no Clojure, Scala, Haskell. < There might not be many jobs, but I think adding (and catering to) these groups will make your brand a better one.
* 60+ leads a month for less than $1 a day < I don't get the math here, you can send 99999+ leads and none of them would make sense to me. I would instead highlight the 100% satisfaction guarantee. And while you are at it, why don't you make it a 3 months money-back guarantee. If people get some good leads, even if none them turns into a job, I don't think many of them will ask their money back. Provided that you move away from the bottom-feeder market of course.
Best of luck!
