I have launched a website for solar industry professionals called iSolarWorld. How can we reach out to them for their feedback and assessment and subsequently promote the website?
On-line promoting of your site, will bring to you many PR specialists, some sales guys, and similar of the sort.
Best way is to investigate and find the real solar professionals, those are tough guys, they talk about wattages and voltages, about USD and square foot of land or house roof. Sometimes they are not much friendly, but are in the core of the business.
all the best
