stuff envelopes for a direct mail campaign - 10,000 envelopes

I'm in need of someone to stuff 10,000 envelopes for a direct mail campaign. The envelopes are standard #10 size and I will provide envelopes that have been pre-printed with our branding. In addition to stuffing the envelopes, there is a requirement for some special handling with the inserts - they must be folded and placed in a specific order. Thanks for your help with this project!
