The fact is that we all start somewhere !!
Since you already have a few clients (even recommended one) just try to do you best to satisfy them (first) and when you finish a project stay in contact with them by sending mails about how they should use you solution, the updates, try to educate you client on the solution, etc...
The goal there is to stay in their mind. So They could think about you or recommend you to their friend, SO THE BIG GOAL IS TO CREATE A POSITIVE EXPERIENCE (like salesforce).
Education is a type of marketing. smile:)
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
