Well, basing on Tsank's draft I have written something I think is clearer and just simpler. The draft proposed by Tsanka is great, but I believe it embraces two things: maintenance AND partly Rules, which have to be created separately. Why separately? Because Rules are something that should be created once for all, to be applied independetly from who makes the maintenance.
So I have written a draft you may see here:
http://cellary.pl/SBH/SBH%20maint%20ctr.docPlease analyse it, sleep with it over night and add/correct your suggestions (and correct my English PLEASE!)
Just few comments:
1. our partner is the company, not its manager
2. payment deadline end November
3. this contract will not have to be presented to any official Bulgarian entity so it does not have to be in Bulgarian
4. contract valid one year to see how it works. We tne may prolong it it change it if we find changes are necessary (life will show).
OK, bye for now.
