Alpine is next door to where I fly at PVU. I know of numerous people who have done their FO program. Any number of things have happened, including-
1-a low time guy like you goes to them and does the FO program. He finishes, then leaves to find out that low time is low time and ends up instructing to build his hours/experience.
2-a slightly higher time guy (500TT) does the FO gig and get picked up by GLA or...well I guess there is no other. Depends on their needs and hiring.
3-either of the guys above find themselves finishing the FO program just a Alpine is hurting for pilots and get hired to remain on. This is certainly the exception and I've only heard of it happening a few times. Now, make almost nothing but build good time and go to a regional.
I would wait to do it when you have more hours, if at all. That price tage is going to be with you a long time if you borrow the money, and you could probably make better use of it getting your MEI.
good luck,
