Depends actually, if you just want to do pentesting then probably do some certifications like OSCP, CompTIA, etc. Once you get those its quite easy to land a interview for pentesting.
Initially job may not pay good but you can build your network and then probably start doing contract works. Most of the pentesters I know make more from freelance/contract work then their jobs. Because mostly those contract/freelance work pays on hourly bases. The initial hour rates usually are somewhere between 40-50 USD but they can go to 120-150 with just after few jobs.
P.S - I might have made it sound a very simple or easy profession but its not :)
