Every Mutual Fund is part of an initiative offered by an organization which we call an Asset Management Company (AMC). You can find their centers easily on the web, if you go to their web sites. An example of an AMC - Reliance Capital Asset Management. You can approach their centres directly and fill up the scheme forms and pay the cheque amount or you could go through an online brokerage like ICICIDirect, where there is no paperwork and the entire transaction can be done online. Only, you have to bear with the 2.25% entry load that will be deducted from your investment.
