Hi,
I think will be able to do what you want. Do not consider my portfolio, since that it is empty because my previous works are performed at the University or under copyright license with R.A.I. (Radio Televisione Italiana), but I implemented a similar project during Bachelor Degree.
I Worked correcting bugs and performing adaptation of exiting web sites.
So, if you accept my bid, I will ask you some more details about all functions you want, in order to give you an analysis with all the tasks scheduled and the time necessary for each one.
The 15 days that I putted should be an upper bound.
Please ask me more informations if you are interested.
Thanks for Your attention,
Antonio Morrone.
