MS Access updates

Job ID: 33971614

Budget: $8 – $15 USD

See addendum at bottom
We have an access Database that we put together over 10 years ago. it was added to, modified and updated to work on newer versions of Access, over the years.
Currently, we add data 5 days a week by collecting the information on paper then going to a desktop computer and add the information into the database.
We want to move the data we already have to a new online database. We want to be able to add data with a phone app or a desktop computer.
We would like 3 levels of access. Level 1, enter data into new record. Level 2 modify data in any record level 3 administrative level, modify database.

We currently use Justhost.com to host our websites. www.brascotech.com . We would like to put the database there.
We are OK moving away from MS Access because it changes regularly and the last time we looked at it, it was very cumbersome to put online.
We can tolerate locking the database to one user at a time, for data entry. If user level 1 doesn't finish and unlock Level 2 can unlock.

There are several entries that are cumulative numbers. For example, a water meter reading, or a gas meter reading. Those entries should be compared to the previous entry and the difference displayed immediately to the user.

We are open to suggestions and would like to see samples of your work.

At this point I am leaning towards MySQL and WordPress as front end
