We are looking for a joomla programmer that has expertise in sef url's.
We are currently using artio joomsef and have the following sef related tasks to perform:

1) analyse what sef component is best: artio joomsef or sh404SEF
- Make scenario's of what tests to perform in order to choose the best component
- Implement both sef components on our test site and perform test to find possible problems

2) Migrate our existing sef component to the new sef component
- Map the existing url's
- Make sure that no url's get lost in the migration
- generate 301 url's for the url's that are moved

3) Develop routers for the chosen sef component
We have several internal components. You must develop routers that work with the chosen sef component (routers must also include canonical url). We will explain you how the new url's must be structured.

Requirements:
You must be familiar with artio joomsef and or sh404SEF and the way they generate url's. So please state your experience with SEF url's in joomla.
