Is there a standard contract used in this arena or should I get my lawyer to draft one up.

There are contracts out there, but I always recommend using a lawyer in order to make sure you are protected.

I'm also interested in how you approached these companies - mail, email or phone.

I have contacted companies by all three. It is just what you feel most comfortable with and what gives you the best results.

Did you set up a meeting or do everything remotely?

It depends on what the companies want. If they are close to me it is nice to meet the people you will be working with.

If they are far away, I have done everything by a combination of e-mail and the phone.

I hope that helps.
