There are a large number of posts with no magic answers. Some suggestions
1) network like crazy
2) tailor every application and cv as much as possible
3) get an admin job in a bigger company and look to move across
4) directly approach lots of smaller companies
5) try volunteering
6) look at public sector and third sector
7) take agency work
8) take short term contracts
9) apply to companies you have some link with or link to industry if you have previous work history
10) keep applying.
