No.

You've got no time or experience presently. You'll have multiple job. If you go corporate, you'll wind up out of work at some point, and looking for other work. If you go airlines, you'll switch or get furloughed at some point. Between mergers, bankruptcies, furloughs, etc, you'll experience change whether you choose to or not.

Don't get caught up in the idea that flight instructing will get you to the airlines, where some other kind of flying will send you somewhere else. Right now you're at the bottom of the experience rung. You need to get experience; get a much as you can.

Banner flying tends to be fairly seasonal. Get it done while you can, do other kinds of flying when you can. Do several if you can. Get paid. Do again.

If you're looking at a regional, remember that it's an entry level job, too; it's entry pay, takes minimal experience to get in, and will be a stopping point as you gain experience and go somewhere else (in most cases). Don't get too wrapped up in trying to decide which job, at this stage in your career, is the perfect fit for getting you down the line. Any job will be a good start; do both, if you like.
