Lifehacker highlights a great list of 100 free or low-cost tools especially made for freelancers. The list includes project management tools, financial services, online storage/data transfer space and professional social networking sites.
Missing from this list are a good RSS reader (I recommend Bloglines or Google Reader), Media Convert, a site that easily converts all sorts of file formats (text, images, audio, video), and Emurse, a powerful resume-building site.
I’ve also been on the lookout for some free or inexpensive project management software. If anyone has any recommendations, please share! You can drop a suggestion in the comments or message me at dansanufATyahoo.com.
