When working as a VA or Transcriptionist one of the ways to get and claim potential clients is by responding very fast. Have your email set to received emails the minute they are sent. As you receive emails asking for quotes, respond as quick as you can or even to a request to use your services, often the early bird will catch the potential client. Clients are impressed by a quick response as it shows you are ready and willing to assist that client.
If you have adsl access then you are able to sit in skype or messenger all day, you have no need to go in and out as these programs barely use any gig space/time. Often clients contact me via skype when a job is urgent, they know they will get a fast response by using this method of communication from me.
