15. Write an informal sales proposal to Karyn Grissom, owner of Mason Office Center. As owner of Green Thumb Planting, an indoor plant service, you are asking Ms. Grissom to become a new client. After visiting the office complex, you determine that the building could use 31 large and 14 medium-sized low-light plants. Your service provides plants and pots, weekly maintenance, and monthly replacement of sickly plants. If Ms. Grissom accepts your proposal, you can install the plantings within one week. For your service, she will pay a $350 installation fee and a $35 maintenance fee each month thereafter. Your proposal should persuade her to sign a service contract. Create and use any additional details or graphics you need to prepare an effective document
