bibliographystyle{unsrt} with custom format of each reference

I’m using bibliography style unsrt in my tex file to sort the bibliography in order of appearance. In addition, I would like to have the reference list to appear like the following:

Articles published in journals
initial(s) surname(s).article. journal,year, volume(bold)(no.): relevant page numbers

Books
initial(s) surname(s).  title.  place of publication:publisher, year

Articles in a contributed volume
initial(s) surname(s).title//author(s).title. place of publication:publisher, year:relevant page numbers

unpublished papers
initial(s) surname(s).paper.publisher: place of publication, year

Thanks in advance
