Hello Wintha,

I echo Grant's comments about the scope of the work and the likelihood that there is a need beyond that of an individual.  I recommend you read this article which outlines the "gotchas" of hiring a so called expert.  Experience is the key, how many different instances and different user stories has this "person" had to run through.  You want someone who has made the mistakes, seen the pitfalls of certain decisions and knows how to solution.  That level of expertise comes with experience, and likely a team.

I am happy to talk through this with you further as you advance your search.
