Help with Company/Client organization program!

Question

Hey guys. I've been working on this project for a while, but since my java skills are not so great, i've been having some difficulty. I was hoping someone could look at the code I had and give me some advice, help and directions.
In the program, the user should be able to create Companies and Clients, as well as their attributes, and save them to two separate Random Access Files ("companies.dat" and "contacts.dat"). The user should then also be able to read back, edit and delete a company or client if they so wish. Each company or client is assigned a Level Of Interest, which I want to take and put into an array, which can later be sorted and viewed in order of increasing interest. I'm not entirely sure of how to go about achieving this, however.
NOTE: The IBIO class was put together by one of my professors to help make i/o easier.
I am also unsure of how to go about deleting, searching and editing the data that is written to the RAF. I hope someone can give me some pointers here. I'll post my code, take a look.
