never met you - this is not bashing you - but I will tell you what not to do.
* do not call or email me weekly for years on end telling me how great your programming is. i don't care - i have too much on my plate already.
* do not join slack channels and pm each person individually telling them you want to start work on their php project.
these two things have turned me off of almost all developers who are not in my immediate area, but especially ones outside my country. please do not harass me. I've had more than a dozen folks - probably nice and well meaning - join our local developer groups and then email everyone in the group individually asking for work. I've had several more that would ping me every time I opened skype with "hello mr mike - we are ready to take on your next php project". Holy tamole... just stop.
What works? I've done a couple of small projects testing out non-us folks. These were either word-of-mouth referrals, or I'd found someone y their blog when searching for something niche. Keep a good clean blog, have a portfolio, build a network of folks who may read your blog or see your portfolio who may recommend your services. It's pretty straightfoward. Do not pester/harass me or my friends. It's the fastest way for me to block you.
