What’s the best and cheapest way for me to advertise for my tutoring place?

I have a list of 5000 students. What’s the bets way for me to get the info for them? If I want to print postcards + stamps, that’ll cost me about $1500 if not more. If I want to do the trifold, will cost me even more. Any suggestions please.

Answer:
If you’ve email addresses, it can be quite easy as you can imagine. If you've got names and their mailing addresses, perhaps locate the schools in their areas and try to see if the school will endorse you. Perhaps some flyers on the community boards around town, postings within the school (they can tell you what they'd allow), listings on Craigslist -those could pay off quite well. There might even be a section on the local npp sites where you can do free listings. They’re all less expensive options, and don't speak to your list directly.. but talk to more than your list.
