If you want a real quality guy you have to go where they go. There are many sites where it's free to post your profile but you have to pay to communicate with others. I would not want to communicate with a guy who was too cheap (poor?) to pay for the service. Also, any man who sends you a message with just one word probably isn't worth your time.

To answer your question about getting more messages, you might want to research how to write a profile that will get the attention of your target audience. Some guys go through and just message any and all women who's photos appeal to them, just on the chance of one responding. Getting tons of messages isn't the objective, I don't think. You want to meet one special guy, so be patient. Quality is more important than quantity. Good luck out there!

Add: A lot of people check sites once a week or less often. Hang in there!
