Work up to it
Everyone will agree the first time its down to mins, we were more nervous than a long tailed cat in a room of rocking chairs. The suggestion about taking a gig flying traffic watch is a good suggestion since alot of them are flying special VFR or having to file in the air when going back in the mornings. A VFR 135 gig other than Arizona where IFR is hard to get would help also since 135 VFR mins are 2 miles and 1000 ft ceilings in uncontrolled airspace. I did as VFR gig for a year where most of the flying was at nite between 2 islands and it was nothing for the clouds to sweep in mid flight. That built my confidence up and when I returned stateside I started flying for FLX in Cessna 210. Still, I was a little more than unnerved the first time I shot an approach to 100ft ceiling and 1800 RVR right at the mins for the approach, but I got used to it over time. Its not for everybody, just dont overestimate your abilities and you will be fine. Just remember before you apply to these companies, they all expect you to fly as long as it is legal alot of times that means to mins. Most training is 3-10 days including ground and flying depending on the company. The company I worked for held no bones about it, they were not there to teach you instruments, only company and 135 policies. 5 days ground school, 6 hours flight training then check ride and then you were off on your own. If possible, file IFR and fly some practice approaches and holds with another pilot and give yourself a buffer like 1000 ft ceilings and as you become comfortable take it down a little at a time. Dont even be ashamed to get an IFR refresher with a sim somewhere, that works wonders in getting up to par. Best of luck and fly safe.
