I'm handling all my work through Freelancer. If you do not have an account there, contact me and I'll send you a referral link with a $20 bonus that can be used towards your project!
Here is my Freelancer.com profile, where you may use the button to hire me.
I've moved on to flat pricing for jobs, but for consulting you're looking at $30/hr.
On-call, meaning I will drop everything and immediately get on your project: $50/day, $100/day on weekends/holidays, in addition to project pricing.
