I think this should work for you

/^29\d{2}\.[0-9][1-9]|[3-9]\d{3}\.\d{2}|[1-9]\d{4,}\.\d{2}$/

Explanation

4 digit >= 2900.01 — 29\d{2}\.[0-9][1-9]

OR

4 digit >= 3000.00 — [3-9]\d{3}\.\d{2}

OR

Any 5+ digit — [1-9]\d{4,}\.\d{2}

Personally, I think these kinds of regexp are kind of silly, though. Can't we just parse it and compare the result numerically?
