You really need to sort out bad projects for something like your first 20 or 30 reviews, after that you can get something like preferred status and see what other post in bids and overall it become much better. Corporate account also possible with membership upgrades and constant promos of memberships, you will not make a lot right away, but while you build up your rep and promote yourself in various ways - money will come to that. Some mistakes and such presents but they fix them each year I would say.
