I don't think there are very capable people on those sites. Most of the projects I was passing on due to my own work-loads were big projects and never completed because of the lack of professional experience by the applicant.
And two, I think most people who use those sites looking for work, are also not as professional as they so astute make themselves look. To me, it is a site for those who want to make a quick buck by doing a half-ass job.
A professional job posting system would and should test your authenticity of your qualifications before allowing you to apply to job positions. There are many job postings offering good pay for professional contractors.
It is because for Big projects needs to work in teams, So it can't be given to individuals and also communication problems etc.
It is a fact that many business projects fail either partially or completely. Many studies demonstrate this. And I suspect that many of those failures are attributed to project management failures.
Thus a project manager probably isn't the best source to evaluate why a broad category of projects fail.
Below is one stat for Apache server, which is a public domain and open source server. From it 60% usage from the top (usage) 10 million web sites in the world. How do those "project managers" explain that success? (There are a vast number of addons for apache.) There are many more examples of this.
One reason individual projects fail is just due to lack of interest when there are very few participants. An initial project needs several dedicated enthusiasts who spend years actively supporting a project until many people start using it. If the first doesn't happen then the second wont.
I am not going to research it in detail but I know for a fact that there used to be a free shopping cart system written in perl. There might be something now in a different language. You can try googling for that.
i am a software developer in Visual basic 6.0. i want to know that may i need any licencee from microsoft to develop any application in vb 6. if yes, please let me inform that from where i can can purchase this paper licence, because microsoft has already stopped the services from vb 6.
VB 6.0 is long dead so I doubt that Microsoft would care what you developed with it. You should also be aware that no business is likely to want to buy applications developed in such an old and unsupported language.
I've working alone in my web business for quite long, and I'm willing to start a bigger project that will need to involve more coders.
I hire frelancer from time to time, but I will need now more than one coder and designer working together in the same project. What could be the better way to manage this team of remote workers? is there any web solutions to manage that? How can I do it knowing that they will not steal the project?
