I suppose I can only give the advice based on what I'm doing right now. I can't tell you if it is going to work, I'll let you be the judge.

First, I would get a name for your business, and buy the relevant domain name, costs no more than about $15 for two years registration. lots of people use their names such as http://www.jkobylkareptiles.com/ , or a fun or memorable name http://www.for-goodness-snakes.com/ . Chances are you wont be able to get any fancy ones like ballpythons.co.uk or whatever, they are worth thousands, and the owners probably wouldn't part with them. Choose a name that you are comfortable using.

Second, I would start getting people to develop trust in your business name. The most cost effective method is to redirect the domain you've just bought to a facebook page. This way you can communicate with people who are fans of your page, keep fans up to date on your project, and generally get people involved.

To attract people to your page create a picture that you can put on your forum profile signature.this way people will over time recognise your 'brand', which as the very first excellent response highlights, will help get rid of the unwanted impression of being an untrustworthy newbie.
