Cheap LVN programs

I've recently become interested in starting an LVN program. I just found one that has night classes. M-W 4-10 but also sat and sun 6-3. I can try to convince my manager to let me do the program and see what he says but i was wondering if anyone knew of a full time m-f or m-th class that's in the evening for LVN. I've read many threads that gave lots of responses but please keep in mind that it's not likely that i'll be able to go to school on weekends and most schools recommended are private which I really can't afford. That brings me to my next issue. I was interested in finding some place that is public that offers that class in a 12 month time period. Every place I have called has been private costing from 20-25 thousand and the few public school I've tried only offer full-time DAY courses which won't work for me. Can anyone that has been there and personally knows any cheap schools that offer night classes during the week please help. I know what I'm asking for is very specific but there has to be something out there. I live in LA county so anything close to that would be great. Thanks.
