you cant avoid spamming... my advice, go to buy sell section, make an intro and website of your company, and make sure:
1) your website is price/quotation and english language "friendly".
2) you reply to anybody make query into your box, (or provide FAQ section in your web) we call this "customers support", even if they havent make any order we still treat them as "potential customers"
3) deliver the service as promised. promise is what you showed in your web, you replied in the email and whatever you say or type or swear.
