Hi ivey,
Here's what I recommend, in addition to the horse-related work..
1. 3 days of aerobic exercise for 30-40 minutes. Any activity will do, bike, walking/jogging, etc. Get your heart rate elevated so you feel I thumping the entire time.
2. Resistance exercise. I recommend exercise tubing if you don't have dumbbells. Tubing is inexpensive and versatile. You can start with a set of three for about $20. They come in colors to denote the tension. If you order them make sure to order the strap that allows you to attach the tube to a door (this is essential for many exercises), and if you want to work your legs, ask for leg straps. Here are some vendors that sell them.

And here's a site with great videos
http://www.body-mind-strength.com/resistance_tube_exercises/resistance_tube_exercises.html Choose 1-2 exercises for every upper body muscle group: chest, back, shoulders, and arms.
Do resistance exercise 2-3 days a week, at least one exercise for every muscle group. (Ab exercises at the end of this post.
3. You'll need to cut your calories. You say you have, but if you're not losing, then you have not cut enough. To lose weight you must burn fewer calories than you consume no matter how much exercise you do. Even if you run a marathon every day you will not lose weight if you consume more calories than you burn. As for weight loss, if you're serious about losing, then I suggest the following
Write down every single morsel of food you eat, and every ounce of beverage with calories you drink. Estimate the portion sizes as accurately as possible, and weigh and measure everything. Get a food scale and measuring cup to do it accurately.
Then go to the following site to figure out how many calories you are consuming
http://www.webmd.com/diet/healthtool-food-calorie-counter 4. Then to this site to estimate how many calories you burn all day (called the 24-hour energy expenditure (24-hrEE)
www.webmd.com/diet/healthtool-fitness-calorie-counter
5. Then here
http://www.webmd.com/diet/healthtool-metabolism-calculator to estimate your metabolic rate. Use the "Inactive" activity level for an additional cushion for underestimation of calorie intake.
Once you know your 24-hrEE, and how many calories you consume, you can modify your intake accordingly, and/or increase exercise, so that you burn more than you consume. For instance, if you consume 2000 calories in a day and burn 1500, then you know you have to either cut back on your calories and/or increase your exercise to turn it around.
If all of this is too confusing, then just do #1 and write down everything you eat. If you do just that you'll lose weight.
