LinkedIn research, browsing and shortlisting profiles

I have an ongoing need for someone to help me short-list people from particular searches undertaken on LinkedIn.

The jobs will look something like this....
A day's task awarded
In some cases half days
These tasks given out regularly e.g. often weekly

The task will be to look through the profiles of people on Linkedin. These would be searched on linkedin using a particular search criteria determined by me. The searches tend to show up 300 to 2,000 people.

I need someone to look through these people and to down select people based on criteria I would determine, for example:
* precise job title matches
* the tenures of employment the person has had i.e. no more than 3 employers in the last 5 years, nor no more than 4 in the last 10 years and conversely not been with their current employer for more than 7 years
* does the person have a degree

Typically there will be 8-10 criteria from which to down selected

Attention to detail is important and when information is provided back to me, I need this to be done so without spelling mistakes nor typos in the names of individuals and employer companies

I want someone who is UK or Ireland based, and for whom English is their first language.
