Need help bidding/budgeting a small house

Please respond if you have experience and contacts regarding obtaining bids, putting budgets together, or developing/building small, affordable houses. I need assistance finishing up a budget for a small house project in North Omaha. Willingness to talk through details and be open to innovation are positives. Short term project, but could lead to other opportunities in the future. If you have a one page summary of experience or projects, please e-mail or text.
