Vending machines

I do a vending business and I search for owners of the locations a lot. Many of them are coming from e-mails. I write offers to set a vending machine to many different places. I want you to write an interesting, remarkable offer for every kind of place that I'm willing to make an offer. I'm not great in this. When I made offers to set a vending machine for churches I wrote following: 'Hello, my name is Vlad. I noticed that you have a big gatherings of Christian people. These gatherings take at least a couple of hours and people often get hungry for that time. I operate vending services in a local area and I have a big variety of food (drinks, snacks, organic food, coffee, I pretty much have everything that can match your needs). I can easily place the machine with a food of your choice. I also can make the vending look in the style of your church (quotes from Bible, the image of Christ, prayers) Please let me know if you are interested in my service.'' That doesn't look good, so I need a proffesional who can of it for me. Here is a list of the places I need forms of offer for: 1. Hospitals; dental offices; small offices of physicians; 2. Churches 3. Small Offices 4. Offices of big companies 5. Gyms 6. Places with any kind of physical activities (Trampolines; yoga; pilates; basketball; et.c.) 7. Parking lots 8. Expensive apartments where there is a lot of space downstairs ( like pool; sofas; gyms for people who live there) 9. Barber shops; 10. Nail salons; 11. Gas stations and Nail salons; 12. Banks 13. Hotels and motels 14. Any kind of shops So, this is approximate variety of places where I want to send e-mails with my offers. I want all of my offers to them to be 1)interesting 2)not too long and not too short 3) Something specific that I liked about them and why THEY need a vending machine 4) good vocabulary, punctuation and style of the letter.
