I want to get top SEO with my new website - video production company

I have just had a new website made by a friend who runs a website design company in Cambodia. The new website is great, however now I need to get to the top of SEO for my video production company based in Southampton and ultimately gain more business. I would like someone who has a good understanding of the sector and preferably a UK based company or person. My current site is hosted on blue host and has a wordpress template so all about google adwords and analytics. I am pretty on top of social media so any tips on that and how to help with the website SEO would be a bonus too.

I want to find out the top 10/20 key search terms for video production and filming services in Hampshire, Dorset and Wiltshire.

Examples of how you made an impact on a companies SEO would be appreciated and even better if you have done SEO for a UK based video production company.

Expected Budget is guide price but happy to pay more if good outcome and service. I would like to talk things through on Skype during the project too.
