Why?  Because it will save you a bundle.  Furthermore, you will look good. 

Getting shirts done "professionally" runs $2-4 per shirt and they probably won't be done the way you like them done.  With practice, a shirt can be ironed in about 10-15 minutes.  The trick is to treat the shirt as a series of shapes and patterns, simply iron each section until the shirt is done.  I like to starch my shirts-- they stay fresh looking longer.  Five shirts per week take an hour and fifteen minutes and I save about $15 per week or $60 per month or $720 per year.

Polishing shoes takes no time at all and saves you $4-7 per pair.  I usually do mine once per month and I can do four pairs in a total of 15 minutes usually while watching TV.  Just spread out some newspaper, use gloves to keep your hands clean (the same kind I use for auto repairs), put the polish on all shoes, then buff the polish off shoe by shoe.  This 15 minutes per month saves me about $240 per year.
