HELP... where do i start

I'm new to forums so hope i don't sound to stupid.

I was hoping you would be able to give me some advice on where to start as I really want to become an ROV Pilot and work offshore.

I'm a female electrician and I work in a city centre hospital and have done for the past 5 years, I also have mechanical experience. I'm currently studying a HNC in Electrical and Electronic Engineering.

It's not a rash decision as I have been thinking about it for a few years now but I'm finding all the info over the Internet and from speaking to people very confusing and conflicting.

I'm in a position now where I want to actively start looking for a trainee position but I'm struggling to find a starting point.

I've saved up the money to do the offshore training and I just need to book the course but I'm scared I will spend a lot of money and never find a position.

I've got myself organised and have a folder full of different company's ready to contact with my CV but I was unsure how to lay my CV out so it stands out from the rest and also I don't know whether to ring the company's or send them an email/letter.

As you can tell I'm in need or guidance.

Is there any help or advice you can offer me or could you point me in the right direction.

Cheers
