Mr. pasador, i guess a visit visa valid for 1 month is ranging from 700 QR to 1200 QR and business visa is about 1200 QR up to 2500 QR. before, i asked how much i will spend if i buy a business visa for my friend in Dubai i called AL Fahd travel in najma in souq ha raj to a certain muzamil he works there in the travel agency and he told me a business visa cost 2500 Qatar riyals. my co worker brother in law, he bought a business visa for 3 months for 1500 QR with a renewal fee of 1200 QR every month without exiting Qatar. the agency or the person to whom you bought the visa will be the one to do the renewal of your business visa. you know its business all people selling these kind of visas is taking some profits and some are asking huge amount of money. try to look for an agency or hotel who can give you visa of your choice with reasonable price and don't give your money immediately most of them are asking down payment you know we don't know some of them are fake and they will take your money and runaway my advice to you is, be smart and transact only to a legitimate hotel or travel agency if you are transacting to a person make sure you knew him. with regards to plane tickets if you will exit to Bahrain you can try and make a booking to any travel agencies here and you will know how much exactly is the fare. and since your only making a booking the travel agency will not ask any single riyal from you. or try to make a booking online the fare is also available there its for your information. because some people they are selling visa with tickets ( packaged ) for huge amount of money. these will serves you an idea how much if you buy separate visa and tickets add these then you can compare it with the packaged 3500 QR tickets and visa they offered you before. by doing that you will have options to take i hope it could help you GOD Bless you brother.
