[AccessD] OT Contract Rates

To all,

Probably not the best place to put this so I do appologise, but am in a
situation in which I have never been or thought about before.  I leave my
current company after almost 11 years this Friday 3rd August, and start
with a new company on the 6th August.  The old company have asked me (no
further details as yet) if I would be interested in working for them on a
contract basis out of hours from my new company (no conflicting interests
of business).  What I would like to know is what sort of rates etc I should
be requesting for support and help for SQL, SSRS, Access, as these will be
systems I have worked on for the last ten years.  The thing is they could
have a situation where they are stuck with an issue, I could log on and
resolve it in minutes, or may take an hour or more, I can work out my own
time, electric etc,  but I am stuck with regards to asking what sort of
charges for my help.

Thank you for any advice in advance.
