Want to manage faster access to Parent's Client list, wher do I start?

[freedon]

The title might sound weird...

My parent's have a big list of client information. They sell insurance (home, medical, life, cars, etc). A few minutes ago a guy came to demonstrate this software that manages client information, specially designed for people who sell insurance. It is costy, around $200 USD per machine, and runs on MS-DOS, this guy says it can be run on win2k and XP. The office machine are a combination of these OS.

My parents have managed with a few Microsoft Excel files. There is 1 file in particular that has the important information (name, company, expiration date, amout, type of payment, etc). All that requieres to be access is Microsoft Excel. This might sound 'lame', but this is a small/medium business, beside it's Mexico, accesing client information with a computer would be considered out of the ordinay .

Of course with this software this person is demonstrating, will make everything faster, granted it will work. So my big question, what programming skills to you need to be able to make something like that? I only a little C and that's it. But maybe it's cheaper to pay someone to program it (maybe..)

Ideas, thoughts, questions?
