Need 50,000 randomly generated numbers! how do I do it?

I have no clue about programming and my knowledge only goes as far as excel! ...was wondering if someone could lead me in the direction of what program to use to do this:

I basically need 50,000 numbers, each 11 digits long outputed into a text file (.txt)
For example 07850069737

The conditions are:

1st digit must be a zero
2nd digit must be a seven
3rd digit can be a 5 or 7 or 8 or 9
All the other digits are random
Each 11 digit number can only appear once in the 50,000.

So the text file will list the numbers like this (one number per line)

07859488334
07984304577
07948498357
07543098434
...


I think it's pretty simple but not sure where to start.

Thanks in advance!

 

Try this : Generate Numbers in PHP

As i mention it's not unique ... so there is some possibilities (Very small) to have duplicate .

 

Just a quick note because you said Excel: A google search will help you solving this task even in Excel, no need for a "real programming language" there

Third hit on Google for "random number excel" :

I can write such applications for a cheap price for you in java if you want.
pm if interested

 

Thanks guys
