Paper-only documents take 7 to 10 business days. Expedited service is a $150 paper-only line and these filings have no paper channel, so there is nothing to buy and nothing to wait for.
Colorado files business organization documents online in real time and the same schedule shows no paper channel for them, so this tier is not something a foreign registration can buy.
If your LLC did business in Colorado before filing, check the Colorado foreign LLC penalty guide first. Back fees can run from the date you started, not the date you file.

Item (2)(f), the order-solicitation item, was amended by HB 21-1124 effective 2021-04-19 to its current electronic-transmission wording.
A virtual mailbox gives your LLC a separate address in Colorado for business mail. Confirm whether the state accepts it for the specific filing field. For banking, ask your bank before buying; it may require your actual operating address.
