New estie

I am a new esthetician who graduated in August. I've taken 1/2 boards exams (still need theory) and I've been booth renting in a salon since July. I have maybe 1 or 2 clients a week 3 or 4 if I'm lucky, but sometimes ill go weeks without any. What is your best advice for starting out and building a clientele. I post on Facebook and Instagram and the posts get almost 0 attention. I do a monthly set of deals to entice new clients but so far none of it has worked. I'm wondering if I wasted $16,000 and should have done something different. I want to be successful but it's so discouraging seeing no progress after 6 months of being at this salon. Help ? (This months Specials and my menu for reference)
