Good luck! I believe photography has been changed forever due to digital technology--less barriers than when film was king and more photographers entering the market. Also we currently are suffering through an ailing world economy and from that luxury services or commercial services like photography are hurting. Plus...many amateurs or misguided talented photographers are offering their services without much business sense or real idea of how much their Cost of Doing Business is, and they are severely low-balling the market. What that essentially offers is $10/hour wage for that photographer at the end of the day (unlivable and unsustainable for a biz) as well as drive down the rates of serious pros. Commercial photography is an established industry with creative fees, licensing fees, contracts, usage rights, etc. If these are ignored you are hurting your fellow professionals and are leaving a ton of money on the table. An image you shoot for a mom and pop biz might get you $500. The same image used by a large company might command $50,000. Same image. Same amount of time invested. But there are long established commercial factors that are the norm at that level.
What I am getting at, is that the photography market is in a period of flux right now. So you better be at the top of your field if you want to make a sustainable and good living from it. You are an artist, a creative professional and a business owner, and you should make a doctor's salary from doing this. Think about diversifying perhaps into some other media. This is just my opinion but I think motion media is going to explode as internet connections get faster and faster and more of our daily media is on computers and smart phones. Things that move attract more attention than things that are static.
Good luck. Rather than investing time into your blog, in my humble opinion I think you should invest it in learning photography. It is a deep, endless well. Plus, right now your name is getting attached by search engines to a blog about an amateur who's dream it is to be a professional photographer. What happens in two year when you start working and that pops up when people are Googling your name? It's not a good image. You want to present yourself like you completely know what you are doing and like you completely know what you are doing, ad infinim. I wouldn't want to hand a 15,000 USD project to someone who has a blog about journeying from an amateur to a pro..and they feel it just happened. I don't want the word 'amateur' anywhere near that person when I am shopping for a professional service.
My 2 cents.
