Tactic advice for a business in a market with falling prices

I'd like to find a freelancer that can create a report (both as a Word Document and a Powerpoint presentation) that provides an analysis of the theoretical tactics available for a business in the following situation and also some examples of businesses that have faced similar situations in the past and applied significant tactics to change their situation and demonstrate a positive result. The situation is very specific, so if exact examples cannot be obtained, then relevant examples of similar situations will suffice. The status of the situation is: 1. The business is in a competitive market with only 3 other major competitors 2. The barriers of entry to the market are significant, making it very difficult for other suppliers to enter the market 3. There are 2 customer groups in the country where the business is operating. 4. Historically due to regulations, the 1st customer group has had a high pricing floor 5. Historically, the 2nd customer group also acted as an opportunity for exposure to the 1st customer group, resulting in all suppliers lowering their prices significantly for the 2nd customer group in order to get exposure to the 1st customer group. 6. Over time the price of the goods offered to the 2nd customer group has dropped to a level that it is significantly below the value offered by those goods 7. The pricing floor associated with the 1st customer group is being removed and the 1st customer group is leveraging the low prices offered historically to the 2nd customer group as a demand to lower the price they are currently paying. 8. The goods being supplied still offer high value to both customer groups and that value is significantly higher than the low price currently being paid by the 2nd customer group 9. There are no other products available that can substitute the value offered by this product (if you need this product, there's no other option available other than the 4 suppliers). 10. The product supplied requires ongoing support from the supplier for up to 10 years, which has traditionally been offered by suppliers at no extra charge. 11. All suppliers also offer other wrap around offerings / services associated with the primary product, which have also historically been offered at no charge.
