UK Visit Visa without Sponsor Letter

I want to apply for UK Visit Visa without the sponsor letter My details are as follows:
Age: 32
Status: Unmarried
Running my own company
Salary $5,000 per month
Nationality: Pakistan

Previously I had applied for UK visa using my cousin's sponsor letter but this time I want to apply for Visit visa without the sponsor letter or I will get the hotel booking.
My travelling history is as below:

1. France (1 week) 1 month ago
2. UK (2 weeks) June 2014
3. UK (3 weeks) Feb 2014
4. France (1 day) Feb 2014
5. UK (4 weeks) May 2013
6. UK (1.5 weeks) Feb 2013
7. Dubai (1 day) Feb 2013

I have strong ties with my country because I have my full running physical office having more than 18 employees and I'm one of the director/partner of this company.

Do you think If I apply without sponsor letter I can get UK Visit visa this time?

sponsor's letter is only required if they are sponsoring the trip - either direct financially and/or by means of offering accommodation. there is no need to include sponsor letter if you are not reliant on them.

all you need to provide in support of your application
a) proof of finance that you'd be able to undertake the trip on your own without relying on anyone or UK public finance
b) strong ties with home country so that you'd return back on completion of the trip
