IMHO, this is the easiest ask for a complete set that I've seen. The world is your oyster! There are so many options that you can choose from in the $1 to $2/chip range.
For $1's, start with
@casinochipper22 , he'll harvest pretty much any chip you desire between CA and LV for $1.50 to $2/chip -->

For $5's, which are a bit harder to snag below $2, check the PCF for sale threads, you just missed two mint IOC $5 racks @ $225/rack -->

For $25's, no better chip than the Indiana Grand $25 @ < $2/chip from numerous sellers including
@Apache - but several other options are currently for sale
For $100's, also PCF sales plus
@Apache , but I'd also consider a Wanted ad for two barrels to see if anything interesting pops up
As an example, I recently assembled this set and the chips average about $2 each (after you take out the awesome Greektown fracs which you don't need/want).
Just do it!
