Hosting Requirements (HELP PLEASE)

I am running the script below on 1asphost.com but it is too slow and unrelible so I am going to move to a paid host.

What requirements do I need. Do i need mySQL? MSSQL? (what the difference anyway?)

I need to send an email from the script. See below. Do I need a certain requirement for that too? Can anyone recommend a good host that will meet my needs?

The script is: (I have removed some of the varibles for simplicity)

<%
'Dimension variables
Dim adoCon              'Holds the Database Connection Object
Dim rsAddComments   'Holds the recordset for the new record to be added
Dim strSQL               'Holds the SQL query to query the database

'Create an ADO connection object
Set adoCon = Server.CreateObject("ADODB.Connection")

'Set an active connection to the Connection object using a DSN-less connection
adoCon.Open "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" & Server.MapPath("research.mdb")

'Create an ADO recordset object
Set rsAddComments = Server.CreateObject("ADODB.Recordset")

'Initialise the strSQL variable with an SQL statement to query the database
strSQL = "SELECT * FROM tbdata;"

'Set the cursor type we are using so we can navigate through the recordset
rsAddComments.CursorType = 2

'Set the lock type so that the record is locked by ADO when it is updated
rsAddComments.LockType = 3

'Open the recordset with the SQL query
rsAddComments.Open strSQL, adoCon

'Tell the recordset we are adding a new record to it
rsAddComments.AddNew

'Add a new record to the recordset
rsAddComments.Fields("company") = Request.Form("company")
rsAddComments.Fields("contact") = Request.Form("contact")
rsAddComments.Fields("title") = Request.Form("title")
rsAddComments.Fields("location") = Request.Form("location")
rsAddComments.Fields("method") = Request.Form("method")
rsAddComments.Fields("phone") = Request.Form("phone")
rsAddComments.Fields("staff") = Request.Form("staff")
rsAddComments.Fields("date") = Request.Form("date")
rsAddComments.Fields("willing") = Request.Form("willing")
rsAddComments.Fields("reason") = Request.Form("reason")

'Write the updated recordset to the database
rsAddComments.Update

'Reset server objects
rsAddComments.Close
Set rsAddComments = Nothing
Set adoCon = Nothing
'This will create the mail sending object.
Set Mail = Server.CreateObject("Persits.MailSender")

'First you need to set the hostname of the mail server you want 'the mail object to use and who the mail is from.
Mail.Host = "myhost"
Mail.From = "ed@myemail.com"   'The From part has the e-mail address.
Mail.FromName = "Ed"   'The FromName is a user friendly name for the sender.

'Now you need to set the destination of the e-mail the address of who it is to.
Mail.AddAddress "ed@myemail.com, "Ed"

'Now you need to just give the actual message to send. 
Mail.Subject = "Solve Research Results"  'You need a subject
Mail.Body = "Company = "+Request.Form("company")+", Contact = "+Request.Form("contact")+", Title = "+Request.Form("title")+", Location = "+Request.Form("location")+", Method = "+Request.Form("method")+", Phone = "+Request.Form("phone")+", Staff = "+Request.Form("staff")+", Date = "+Request.Form("date")+", Willing = "+Request.Form("willing")+", Reason = "+Request.Form("reason")

'Now you just need to send it...
Mail.Send

'It is always good to check for errors, the MailSender object supports the Err object.
If Err <> 0 Then
Response.Write "Letter was not sent due to the following error: " & Err.Description
else
Response.Redirect "/thanks.htm"
end if

%>

Many Thanks,
