Hello,
Having 9+ years of exp and interested.
Does have OsCommerce experience.
To implement the addon, I will first have to copy entire project on my demo server and will make changes there.
Existing website can have some bugs or issues those will not be taken care off in this assignment.
Its just implementation of the the addon that's part of the scope and bid is for that only.
Once addon is installed on my machine, you will release second milestone of 50% as first 50% is upfront.
Thanks,
Ranjan
