Data Recovery - Deleted Table

Hello We have one Live project. The last backup of data we have is quie old (even the scheduled data backup from Hosting Provider is of no use). Some user's data was deleted accidently today. This data was created in last 3-4 days. Now we want to recover that data. We are using MySQL with MyISAM structure. Hosting is provided by [login to view URL] on Shared hosting (so limited / remote access only). Now we are looking for someone who could help us in recovering thos accidently deleted data. We can provide the time from which to which data was deleted. Thank you.
