Access Programmer, Office 365, sharepoint,

Need an experienced Microsoft Access admin to fix a database. We utilize Office 365 so having familiarity on how Access interacts with Sharepoint is a requirement. Would be helpfull to have experience with office 365 apps and utilities, maybe there are other instruments. We are a studio offering yoga classes. We need several formulars to choose, where we can add new contact data to the common contacts (like " trial hour") , "interested" or "registration", also payments over the year (once, monthly) and statistic reports. trial hours should be added to calendar. Actually we use several excel sheets. Unfortunately leads this to unnessecary repeatedly actions. Also we have a checkin. Here we have lists with names, start and end of contract, etc and dates. we manualyy update them , print them and the teacher fill out who is there. Step on the computer must be printed again. Updates of participants should happen automatically and there should be a frontend where at the checkpoint the people can be checked in at a tablet. Teachers should have access to limited things. If you think you can find a solution we will show you everything in detail.
