Haba, how the requirements huge now? Laravel 4 & 5 are pretty much the same and Git is pretty much standard. Bash & CLI are very minor addons as well.

What is common with regard to abilities right now?

These Indian dudes are killing the company I work for. I'm constantly telling them that there are better programmers from Nigeria than in India with better comms skills but I lack the "proof". So, if one wanted to hire a freelance programmer in Naija, where is the best place to start:

Project:
Laravel 4 & 5
Homestead (NOT *AMP)
Git
JS/jQuery
Bootstrap 3
Intermediate CLI ability
Bash

Is the Blackberry World Edition 8830 compatible in the Nigerian GSM environment? It has both cellular and GSM capabilities but the cellular is primary. however, the GSM function is unlockable

Generating a unique id for ur users as well as a unique password isn't a problem and u do not need to actually code a queue. The internal workings of the mysql database will handle that on its own. To generate uniquness I usually use a combination of three factors: Full timestamp of the entry, an auto_increment column which should be the primary key and the users chosen username and password. Combine this info in two separate columns and encrypt with any secure mode u desire. Make sure you separate the username & password data. When a user logs in through your secure form input the code will verify against the encrypted username & password in ONE-WAY fashion.
