question on filing a lien in Michigan

We are a GC from MI, did a project for a LL at a mall in Lansing, MI. The Landlord still owes us roughly $53,000. If we send them an Intent to Lien notice, do we only have 10 days then to file the actual Claim of Lien? And, when does the 10 days start, from the time we send the Notice through your service or from the time they receive the Notice? We completed the project in June but there was an issue with the glass that took a while to get the subcontractor back to complete his work. Not sure if the LL is now dragging his feet , ie: playing games with paying us just because the glass correction work took so long ...
