I was fixing to send some money to Nepal but Muncha said they don't have their service available in Texas (http://www.muncha.com/money/) I don't know what they were thinking when they didn't decide to add Texas at first. Well, can anyone help a brother out and direct me to some websites like Muncha who doesnt charge anything if it's over 2500?

And you'll be in big brother's list to be watched for at least six months.
Banks or any other transfer agencies will make a SAR (suspicious activities report) for transactions over 10K. Breaking the the fund into smaller chunks? They are smart too..they know it. They watch all the activities over a period from a person. After 9/11, they are really worried about the terrorist funded by US money. So any big transaction get reviewed from that standpoint.

Use any major US bank if you really want to send big chunk of money to Nepal. Make sure you send dollar from here. Not Nepalse currncy. They will give you low exchange rate here is US if you transfer nepalese currency. So just ask them to send dollar to Nepal. And when it gets there , you get the echange rate which is the buying rate of dollar in nepal. The exchange rate is higher than moneygram western union or any other thirs party services. You might end of paying $45 fee to intiate transfer from here through bank but trust me you will save a lot on echange. This is my personal experience. Done this many time and never had any issue. No suspicious report no legal issues. Just indicated reason as family support while doing wire.
I want to suggest one more time, send dollar from here . Do not intiate echange is US. They will ask if you want to send dollar or local currencies and go for dollar.

@ daru. You must have done echane here at bank of america. Thats the reason you got $1= 93. I made a wire last week and they got $1= 98... The exact rate that Nepal bank has as buying rate in nepal on particular day you receive your money.

UPDATE:

i ended up doing wire transfer through my bank. They charged me 45 bucks and since they dont carry Nepalese Rs they sent the amount in Dollars. Thanks to all for your suggestions and Mailo bhai knows what he is talking about.
