I've not been around all day - very stressful day at the office! You have already received good advice, and if I were in your shoes I would certainly seek another opinion to see what other solutions are out there. The key things to bear in mind are:-
1 Is an IVA really important to me? Have I fully considered the merits of other solutions such as bankruptcy proceedings or debt management.
2 Can I afford the payments being suggested, and have I provided for all known expenditure and contingencies. Try and find your "gut level" feel for the contribution level you feel that you can afford, and do not be tempted to say that you can afford more - as the reality is you won't.
3 Unless your suggested offer of a 1 year full and final solution is based upon third party funding, and you have no disposable income to offer ongoing payments, this is unlikely to be accepted. The suggestion that you could pay one years worth of contributions and then realise an endowment policy will not work. If you can afford payments for one year, you can afford them for five - in the eyes of your creditors.
As you seem so uncertain which way to turn, seek more advice and opinions. A pattern will soon emerge, and you will know when you find an IP you feel comfortable with. Good luck in your search.
