Amending some artwork files and creating a new artwork

I need to get artwork amended for three leaflets, a small ad (to create three versions bsically with diferent phone numbers), and an A2 poster. All are based on an existing design and basically need copy amends.

I will need the ads done asap (i.e. by the 14th.

Please not I don not need design or creative thinking for this - simply opening up some indesign files, making copy amends and creating versions.
