Any suggestion what is the wordpress theme in this website: www.loseweightfast.net And what plugins i need?
You should be able to go on freelancer.com and get someone to clone it for you for $30. Make sure you state that you want a layout for the homepage, blog posts, and "pages" because if you don't specify, you won't get what you want. It looks like they adapted the WP 2011 theme here.
I can do a similar design that is clean light and fast but not going to beat a1.premium's price. My price would be twenty five bucks. Contact me if you like, I will put up my design on another domain I own and you can look it over and I can make any revisions you would like then if you are happy you pay me. here is one I did not too long ago: http://oaktrees.us/ it has a transparent body - I used 80% transparency. if I made it 100% it would look just like the loseweightfast.net site - no background on the main content section, just all one color with the sidebar. I see they are using some kind of redirect for the affiliate links. I have several plugins I'm using on a few of my wordpress sites that I could recommend for this. Here is one I use: http://w-shadow.com/blog/2007/07/28/link-cloaking-plugin-for-wordpress/ loseweightfast.net does have a contact form, hit them up and ask who made their theme. They may tell you. ###
Very nice design, but yes, it is a custom one but it seems like both the people above and also those at freelancer would be only too happy to help you! Good luck!
