I Need SEO work on my website, to get pages to the top in Google Searches

I have 3 pages: www.pcworkshopslondon.co.uk and http://pcworkshopslondon.co.uk/java-courses/ and http://pcworkshopslondon.co.uk/courses-page/
These pages should be optimised to go to the top in google searches.
Key words that should bring these pages to the top of Google Searches :
Java courses London, Java programming courses, Java courses, Java training, Java training London, java london, java certificate courses, etc.
I want to optimise on Java courses. All other courses are not necessary.

To get this task:
1. Please describe what you need to do the task.
2. What will you do to get the pages to the top of Google
3. Please specify what you would do if you need to work with me in the long term.
4. Please provide case studies of sites that you have successfully optimised.
5. Please make sure that you describe clearly what you will do to optimise these pages, because I have had a few less favourable experiences with some contractors

Thank you very much, I look forward to your proposals
Kind regards
Sarah
