Decide what your motivation is
It appears you have accumulated some decent core technologies which are certainly transferable.
In IT, people want to progress for three main reasons: more money, greater responsibility or the chance to learn a new technology. Preferably, you would find a position that offers all three, but what are your key motivators for moving? What is "progression" to you? Assess your needs for your next role so you can aim to apply for jobs that offer these to you.
My immediate response would be to aim for an IT or support manager's position with a user base of between 100 and 250 users, perhaps with an increased management responsibility and a slightly bigger budget.
This would increase the chances of improving on your basic salary and enhance your interest in learning new skills and technology. If it is purely technical roles you are looking for, aim for second- or third-line network or server support positions within small and medium-sized companies.
When searching for jobs on the internet, vary your search by trying different word combinations, different areas or different industry sectors to improve your chances.
You can also try approaching firms in your area directly, as a large proportion of job vacancies are not advertised.
