Want someone with affordable hourly rate to:

1.
Upgrade to latest version

2.
a)
I have 2 tables and in table1's one field need to display all the items from table 2.

Table 2:
id table1_id attribute value
1 2 attribute1 3
2 1 attribute2 2
3 2 attribute44 88

Table 1:
id name table2_values
1 name1 attribute2=2
2 name2 attribute1=3; attribute44=88

b)
Fillter in table1 (or in table2 if not possible in table1) all items that mach to criteria where attribute1<5 AND attribute44>50 so you see instantly in table1 only the id=2 as the id=1 even doesn't have those attributes.

3. Relational tables where you can click to open another table with that ID.

4. Set up WYSIWYG editor

5. etc. etc.
