I am going to be mailing in bids to many different places around town, but i need to have a bid proposal. What are some things that you need to point out in the proposal? I am looking for it to be a very professional proposal and just want to know what to include in it. I have never really used this approach to new work before, but i figured i would give it a try to see if I can get new work. I am just needing to know if I should be writing a letter and then attaching a bid to it? How would you guys go about doing this?
