Part time Employment

Can anybody help me?? I am a full time mature student and a single
mother of two young children of 4 and 5 and ideally I am seeking
employment of an administrative nature only to work every second
weekend when my children are at their dads as I really don't have any
more free time but do need the extra money.  I live in West Lothian so
something within a 20 mile radius would be ideal as I do drive, hope
someone can help me with this.

Thanks
Wendy
