Much depends on the reason your 485 paperwork was initially denied. It is impossible to ascertain your options w/o reviewing the denied 485 paperwork.
You need to have an experienced immigration attorney review your approved labor certification, approved I-140 and denied 485 paperwork to determine whether new 485 paperwork may be filed, whether you may pursue immigrant visa processing and/or other options to continue with your green card process.

Like my colleague, I assume you mean the I-485 was denied. However, it would be useful to know exactly what was denied. If less then 30 days have passed, you may be eligible to file a Motion to Reopen. This option could potentially be cheaper than a new I-485. However, consultation with an experienced immigration practitioner is advised.
