Hi Nadya,
with Arnica Webreport you can do it very easily:
1. create a report for each SP
2. create report #4, which would not have its own data, but joins the three others
3. specify CSS, business rules, hyperlinks, etc. or additional processing if required
4. check boxes: PDFOutput Enabled, EMail enabled
and just run it!
