Brochure and supporting sales letter(s)

Content writing for 4 page brochure with possibility of extended work. Sales letter to support brochure mailings required - leading edge targeted at a traditional industry. No pressure! Market entry strategy so its virtually certain they'll be a need for a follow mailing and possible 1/2 page brochure.

For clarity, bids are invited for the 4 page brochure and 2 sales letter. Indication of pricing for the extended work would be very helpful.

Happy to expand on request.
