If you're talking about a small budget (~$400) and are asking for someone with the kind of experience you're indicating...that's generally considered a red flag for a problem client.
If you're also demanding an NDA for a 'small project', the paranoia indicated is another 'red flag' -- generally people who try to hard to cover their asses always feel like they're getting ripped off.
Top that off with, 'If you post here, I'll know you're illiterate', and seriously...I hope you don't think you're actually going to get a reputable, capable developer.
I'm not trying to troll or flame here, but I think you need to reconsider your approach to getting this project done.
1.) Small budget - yes. It is expected to increase over time once the site gets the basics up and running for maintenance and improvements. If I had more BTC to offer, I would.
2.) PHP and javascript experience is cheap in my experience... it's the knowledge of BTC that adds value for me vs. something like scriptlance/outsourcing to India
3.) In my general line of business practices, NDAs are standard for every part of the work I do for others and they do for me; refusal to sign an NDA is generally a red flag for me as a client
4.) Hoping to get a capable, and literate developer. Reputable is nice, but capable of doing the work and following basic instructions (eg where to contact me) are more important to me.
5.) No worries - appreciate the feedback.
NDAs are only scary if you're a.) paranoid or b.) malicious. I doubt many people here are malicious. In a world where certain ideas make money, and other ones don't, if you don't protect your ideas others are free to profit from them. An NDA just gives a small amount of legal recourse.
