First off, every one here has offered you good advice but you take it as insults and started crying. Doing all the chores day after day does NOT make you a good rider. Haha, nope. It only teaches you responsibility and having a good work ethic. But it can give you muscle and exercise, hauling hay and buckets, etc. etc.
Now, if you will please act like a sensible person, read through all the posts again and find the good advice in each one. And also hear me out.
No one here is trying to be mean -- if they are then ignore them -- we are looking out for you and your horse and offering some good advice.
*where to get a saddle
Whatever is decent and will work for you.
*how to introduce English to a Western horse
Find a good trainer that knows what he/she is doing. Switching a horse from one discipline to another may sound simple and easy. But there will be tack changes. English saddles are lighter than Western so imagine how strange that would feel to him. Plus different cues, shorter stirrups, etc.
*what tack do ya need
Very basic question. If you are SO experienced you should know what all tack you need. Saddle, bridle, halter, reins, breastcollar, lead rope, etc.
* how to budget the spending
Write on a paper how much you can spend. Then take that and make up costs on how much items will cost. A saddle can probably be $500, bridle maybe $50, reins $20, etc, etc. But prices will vary depending on your area or store, whatever.
